MAN-SC/-LC Digital Pressure Gauges for Industrial Measurement
The KOBOLD MAN-SC/-LC is a digital pressure gauge that pairs precision sensor technology with a choice of battery-powered (MAN-SC) or IO-Link-enabled (MAN-LC) operation. Engineered in Germany for mechanical engineering, hydraulics, pneumatics, and process industry applications, it covers measuring ranges from -14.5 to 23,200 PSI with 0.5% accuracy at reference conditions.
This dual-configuration approach covers portable service work as well as integrated industrial automation, with both models sharing the same proven sensor technology and measurement accuracy.
Dual Model Approach for Application Versatility
The MAN-SC operates on a standard 9V battery, delivering up to 2.5 years of operation, ideal for field service, mobile equipment monitoring, and installations where external power is unavailable. The MAN-LC runs on external 24 VDC power (18-32 VDC supply range, power supply not included) and includes IO-Link communication for automation systems requiring real-time data transmission and remote parameterization.
Advanced Measurement Technology and Accuracy
The MAN-SC/LC utilizes ceramic sensors for measuring ranges up to 10,000 PSI and stainless steel sensors for ranges exceeding 10,000 PSI. They deliver 0.5% accuracy at reference conditions (70°F / 21°C, 860-1060 mbar, less than 90% relative humidity, non-condensing), with repeatability of ±0.2% of reading and temperature influence of ±0.25% of full scale per 18°F (10°C) change.
For measuring ranges up to 10,000 PSI (700 bar), an optional integrated NTC temperature sensor provides simultaneous temperature measurement from -22°F to 185°F (-30°C to 85°C) with ±2.7°F (±1.5°C) accuracy in the 14-176°F (-10 to 80°C) range, adding diagnostic capability beyond pressure-only instruments. Long-term stability remains within ±0.2% of full scale per year at reference conditions.
Installation Flexibility with Rotatable Design
The MAN-SC/LC housing rotates 360° around the sensor axis, while the display module adjusts in 90° increments, providing installation flexibility for confined spaces and optimal viewing angles. This design eliminates the need for special mounting brackets or adapter fittings.
Available process connections include G 1/4 and G 1/2 threads (EN837), 1/4" NPT and 1/2" NPT threads (ANSI/ASME B1.20.1), plus numerous specialty connections for diaphragm seal assemblies. The optional rubber protection sleeve provides impact resistance for rugged operating conditions.
Comprehensive Display and Interface Features
The 5-digit LCD display with 16 mm digit height provides clear pressure readings under direct sunlight and low ambient light, and the MAN-LC model includes a white backlight for improved visibility. Three capacitive touchpads enable intuitive menu navigation and parameter adjustment without mechanical buttons that could fail in harsh environments.
The display simultaneously shows primary pressure values and secondary force calculations, with selectable measuring units including PSI, bar, mbar, kPa, MPa, kN, N, torr, inHg, inWC, mmWC, or user-defined units. Peak memory continuously records minimum and maximum values, and password protection prevents unauthorized parameter changes in critical applications.
IO-Link Communication and Smart Integration (MAN-LC)
The MAN-LC model provides a fully configurable device with the option of full IO-Link communication or two configurable outputs including frequency, analog, or switching options. IO-Link mode provides full IO-Link V1.1 communication with COM2 bit rate and 10 ms minimum cycle time, enabling remote parameterization, diagnostic access, and integration into Industry 4.0 environments.
If not utilizing IO-Link, two universally configurable signal outputs support 4-20 mA or 0-20 mA current signals, 0-10 VDC or 2-10 VDC voltage outputs, frequency outputs up to 1000 Hz, or binary alarm outputs with NPN/PNP/push-pull configurations. The optional relay board (ZUB-MANS-KON1/2) provides two potential-free SPDT contacts rated 30 VAC/DC at 1 A for direct process control.
Applications Across Industrial Sectors
These digital pressure gauges are used in mechanical engineering and plant construction, pump and compressor monitoring, hydraulic and pneumatic circuits, process industry installations, and load capacity measurement applications. The tare function enables zero-point adjustment for differential pressure measurements, and service technicians value the battery-powered MAN-SC for portable diagnostics and field calibration.
The force measurement mode converts pressure readings to force values based on programmable reference areas, useful for tensile load testing and press applications.
Proven Reliability and Quality Standards
Manufactured to German quality standards, the MAN-SC/LC digital pressure gauges undergo rigorous testing including 20 g shock resistance (DIN EN 60068-2-27:2010) and 5 g vibration resistance from 10-2000 Hz (DIN EN 60068-2-6:2008), while the IP65 protection rating ensures reliable operation in dusty and wet industrial environments.
Wetted parts include either ceramic or 316Ti stainless steel pressure sensors and 303 stainless steel process connections with options for NBR, FKM, FFKM, or EPDM gaskets to match media compatibility. Overload capacity reaches 3x nominal pressure for ranges up to 580 PSI (40 bar), protecting against pressure spikes.

KOBOLD USA provides technical support from Pittsburgh, Pennsylvania, with application engineers who assist with product selection, installation, and troubleshooting. Available accessories include M12x1 cable assemblies in various lengths, rubber impact protection sleeves, relay retrofit kits for the MAN-LC model, and extensive diaphragm seal options for corrosive chemicals, high temperatures, and viscous fluids.
Common Questions about MAN-SC/-LC - Digital Pressure Gauge
Pressure is sensed by a ceramic or metal measuring cell and processed by the electronics, which show the value on a five-digit LCD. According to the operating manual, the device measures, monitors, and remotely transmits pressure-dependent operating processes in machines and systems, and the MAN-LC version adds two parameterizable electrical outputs.
Standard measuring ranges span -14.5...0...23,200 PSI, corresponding to -1...0...1,600 bar in the metric ordering codes, and special ranges are available on request. Choices include vacuum and compound ranges starting at -30 inHg, gauge ranges from 0-10 PSI upward, and absolute pressure versions per the ordering table.
Power and connectivity separate the two models. A 9 V block battery runs the MAN-SC, which offers programmable sleep modes to maximize battery life. The MAN-LC draws external power (18-32 VDC via M12x1 connector) and adds a white display backlight, IO-Link capability, and two configurable signal channels.
Typical lifespan at 68°F (20°C) is up to 9,000 hours, about one year, with a 600 mAh alkaline 6LR61 battery, and up to 22,500 hours, about 2.5 years, with a 1,300 mAh lithium version. Programmable sleep modes lower current draw to roughly 13 µA in deep sleep.
Two universally configurable channels can be set as current signals (4-20 mA or 0-20 mA), voltage signals of 0-10 or 2-10 VDC, free-scalable frequency signals up to 1000 Hz, or NPN, PNP, or push-pull alarms. Alternatively, OUT1 carries IO-Link V1.1 at COM2 bit rate and a 10 ms minimum cycle time.
Standard options are G 1/4B and G 1/2B threads to EN837, plus NPT threads in 1/4" and 1/2" sizes to ANSI/ASME B1.20.1, machined from 303 stainless steel. The ordering table also lists bottom connections with cooling fins, M16x1.5, M20x1.5, M6 female, and 7/16-20 UNF options, plus diaphragm seal assembly.
Media contact is limited to the sensor and the connection: aluminum-oxide ceramic cells serve ranges through 10,000 PSI, while fully welded 316Ti stainless steel cells handle higher ranges without a gasket. Connections are machined in 303 stainless steel, and gasket choices include standard NBR along with FKM, FFKM, EPDM, and PTFE.
Yes, when ordered with output code 20 or 40, which adds temperature measurement on ranges through 10,000 PSI (700 bar). The built-in NTC sensor reads -22 to 185°F (-30 to 85°C), holds ±2.7°F (±1.5°C) accuracy between 14 and 176°F (-10 and 80°C), and updates on a roughly 45-second measuring cycle.
Protection class is IP65 per IEC 60529, with tested resistance to 20 g shock (11 ms, DIN EN 60068-2-27:2010) plus 5 g vibration across 10-2000 Hz (DIN EN 60068-2-6:2008). Permissible ambient temperature runs 14 to 140°F (-10 to 60°C), storage spans -22 to 176°F (-30 to 80°C), and an optional rubber sleeve adds impact protection.
Yes. Force measurement mode calculates Force [N] = 10 x AREA x measured pressure, where AREA is a programmable reference area in mm² and pressure is entered in bar, according to the datasheet. Results can display in kN or N, and the tare function zeroes the reading for differential measurements and pull-tester load checks.
