HMU series basic pressure sensors The HMU pressure sensors provide uncalibrated and uncompensated analog mV output signals. They feature an increased media compatibility to measure gases and liquids. Very small SIL and DIP housings allow for space-saving PCB-mounting. All HMU pressure sensors can be modified according to customer specific requirements. (1, 2) Features Media compatibility Applications Pressure ranges from 100 mbar to 10 bar, Industrial controls High pressure port: 1 psi to 150 psi gage or differential pressure Pneumatic controls To be used with gases and liquids which are (1) Increased media compatibility Environmental controls compatible with the wetted materials (high Wide operating temperature range HVAC temperature polyamide, ceramic AL O , epoxy, 2 3 SIL and DIP housings Instrumentation fluorosilicone, glass, silicon). Analytical instruments Low pressure port: Medical devices To be used with non-corrosive, non-ionic Certificates working fluids such as clean dry air, dry gases and the like. Quality Management System according to EN ISO 13485:2003 and EN ISO 9001:2008 RoHS and REACH compliant Specification notes (2) Sensor is specified in air, changes in sensor behaviour based on physical (1) All wetted materials are selected to give a high level of media compatibility. effects caused by the specific media can occur. Weight of the media and Media compatibility refers to media inside the pressure port and lid. wetting forces can influence the sensor characteristics. Improved media compatibility on high pressure port (backward side of sensor chip) since media has no contact to electronic components. Nevertheless tests with the media used in the specific application are recommended.
