Our pressure gauges (mechanical pressure measuring instruments) for gauge pressure, absolute pressure and differential pressure have proven themselves millions of times over. For the optimum solution for the most diverse applications, there is a choice of measuring systems in Bourdon tube, membrane element and capsule element technologies. The manometers cover scale ranges from 0 ... 0.5 mbar to 0 ... 6,000 bar and indicating accuracies of up to 0.1%. Pressure elements made of copper alloys, stainless steel or special materials are available for different requirements in industrial and process instrumentation.

A pressure sensor (or pressure transmitter) converts the physical quantity “pressure” into an industrially standardised signal. In addition to a wide range of pressure sensors for general industrial applications, we offer special versions for refrigeration and air conditioning technology, the food industry, mobile machinery, medical gases, and also the semiconductor industry. Our range of pressure sensors includes accuracies from 0.008 %, measuring ranges from -1 bar to 15,000 bar, digital interfaces such as CANopen and IO-Link, and also various international approvals, including for hazardous areas.

Pressure controllers are electronic controllers that quickly and automatically deliver a pressure based on a supply pressure. Due to their high accuracy and control stability, pressure controllers are particularly suitable as a reference for production lines and laboratories, to perform automatic tests and/or calibrations of all types of sensors.

Our portable pressure gauges set standards in research, development, production and service. Discover the wide spectrum of mark leading portable pressure gauges at LHM Instrumentation. Outstanding performance. Premium quality. Correct advice.

Digital Pressure Gauges are portable measuring and calibration instruments for mobile use for accurately measuring and recording pressure profiles. Interchangeable pressure sensors with measurement ranges of up to 8,000 bar are available for the instruments. This makes handhelds particularly suitable as test instruments for a wide range of applications in the most diverse industries. The data recorded in the handheld can be evaluated via PC software
