product description Pressure transmitter TST-SMO
The TST-SMO pressure transmitter series is designed for pressure measurement in applications requiring increased vibration and EMC resistance. For example, for the special requirements in mobile hydraulics and automotive engineering, with special measuring tasks in brake systems or diesel and natural gas engines.
The TST-SMO pressure transmitters are characterized by increased shock resistance of 1000 g according to IEC 68-2-32 and increased vibration resistance of 30 g according to IEC 68-2-6 and IEC 68-2-36. TST-SMO pressure transmitters are suitable for measuring ranges from 0 ... +4 bar up to 0 ... +4000 bar. A variety of commercially available process connections and electrical connection plugs can be combined with the usual analogue output signals. Optionally, the TST-SMO can be equipped with a throttle to reduce pressure peaks or a load-dump protection module. This module protects the pressure transmitter from damage caused by voltage peaks that occur during rapid load shedding on an alternator or generator.
