The Texas Instruments Sensors & Controls group has introduced a low-cost, hermetically sealed pressure transducer/transmitter, available in both 4-20 mA or voltage outputs. With electromagnetic compatibility (EMC) protection at levels to 100 V/m, the transducer also features vibration tolerance rated at 20g (up to 1 kHz), a wide operating temperature range of -40 to 135C, and pressure ranges from 50 to 750 psi. Applications include medical systems monitoring and pneumatics, HVAC regulators and compressors, pumps and flow systems used in process industries, and hydraulics for off-road vehicles.
