HMA series amplified pressure sensors The HMA pressure sensors provide amplified analog output signals and utilize precision digital signal conditioning to achieve high accuracies. The sensors oerff an increased media compatibility to measure gases and liquids. 5 V and 3 V supply versions are available. Very small SIL and DIP housings allow for space- saving PCB-mounting. All HMA pressure sensors can be modified according to customer specific requirements. (1), (2) Features Media compatibility Applications Pressure ranges from 2.5 mbar to 1 bar, 1 psi Industrial controls High pressure port: 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 Analog output HVAC temperature polyamide, ceramic AL O , epoxy, 2 3 Precision ASIC signal conditioning Instrumentation fluorosilicone, glass, silicon). (2) Calibrated and temperature compensated Analytical instruments Low pressure port: SIL and DIP housings Medical devices To be used with non-corrosive, non-ionic working fluids such as clean dry air, dry gases and the like. Certificates Quality Management System according to EN ISO 13485:2003 and EN ISO 9001:2008 RoHS and REACH compliant Specification notes (1) All wetted materials are selected to give a high level of media compatibility. (2) Sensor is calibrated in air, changes in sensor behaviour based on physical Media compatibility refers to media inside the pressure port and lid. effects caused by the specific media can occur. Weight of the media Improved media compatibility on high pressure port (backward side of sensor and wetting forces can influence the sensor characteristics. chip) since media has no contact to electronic components. Nevertheless tests with the media used in the specific application are recommended.
