with over 40 years of experience in designing and manufacturing of oil-filled pressure sensors, Micro Sensor offers wide range pressure sensors with gauge, absolute and differential pressure. Our pressure sensors offer different diameters, ranging from 0.07bar to 1000bar (vacuum is available), materials such as SS316L, Titanium, Tantalum, and Hastelloy C, etc.

Basic Piezoresistive Pressure Sensors

Piezoresistive pressure sensor Micro Sensors offered is with increased media compatibility for liquid fluids pressure measurement. The pressure sensor outputs mV-output signal and is a wide temperature compensated. The pressure ranges from 70 mbar to 1000 bar and from 1 to 1450 psi. These basic piezoresistive pressure sensors can be customized to unique materials, constructions and pressure ports, etc.

Anti-corrosive Pressure Sensors

Anti-corrosive pressure sensors Micro Sensor supplied are specially designed for corrosive liquids and gases pressure measurement. The pressure sensor diaphragm is Tantalum, Titanium, Hastelloy C and stainless steel 316L, suitable to measure seawater or corrosive media such as acid etching, stress corrosion, alkali, chloride, chlorine organism, nitric acid and vitriol, etc.

Differential Pressure Sensors

Differential Pressure Sensor from 350 mbar to 35 bar is an OEM silicon pressure sensor based on piezoresistive principle. It has optional outer resistors temperature compensation and all welding constructions, possible for various fluid media. Differential pressure sensors can be widely used in the industrial process control field etc., for differential pressure measurement.

Micro Sensor provides a wide range of pressure transmitters and transducers for process control, marine, industrial gases, food and beverage, HVAC and telemetry, etc. Product family includes pressure transmitters and transducers, level transmitters, MDM3051S series, switches and IoT wireless remote monitoring devices.

Pressure Transmitters

Micro Sensor provides a wide range of pressure transmitters and transducers for process control, marine, industrial gases, food and beverage, HVAC and telemetry, etc. The pressure transmitter ranges from 100bar to 1000bar, outputs analog 4-20mA DC and voltage 1-5VDC, etc. These pressure transmitters are certificated with ATEX explosion-proof, Exd as well as UL, suitable for hazardous environment use. Custom design available.

Digital Pressure Transmitters

Digital pressure transmitter and pressure transducer output digital I2C, RS485, MODBUS and HART signals for applications. Micro Sensor offers low power consumption digital pressure transmitter with 3.3V power supply.
