PTX21 Pressure Transmitter
Brand: Status Instruments
The PTX21 pressure transmitters are high accuracy, robust, 2-Wire current output pressure sensing devices.
Sensing is by a piezoresistive element, oil filled, and enclosed in an all welded stainless steel (316L) housing. Silicon filling and Viton seals are available as standard, with other options to order.
Span and Zero potentiometers are provided for fine adjustment or periodic re-calibration.
Gauge, absolute or sealed gauge types are available and all models are reverse polarity protected. Ranges are to Din standard (in ratios of 1, 1.6, 2.5, 4, 6,) e.g. 100, 160, 250, 400, 600 mbar and 1, 1.6 bars etc. with custom calibrations available in all pressure measurement units.
High medium temperatures, up to 150° C (illustrated). Lightning (surge) protection to EN 61000-4-5 and Intrinsic Safety options are all provided.
