Excellent Factory Directly Differential Pressure Level Transmitter

High accuracy
±0.2% accuracy for all calibrated spans is the standard feature for all AP models covering 10 to 3000kPa. The compositive monocrystaline piezoresistive sensor assures this accuracy for all elevated or suppressed calibration ranges without additional adjustment.

Application flexibility
Various options that render the CXT suitable for almost any process applications include:
–Full range of hazardous area approvals
– Built-in RFI filter and lightning arrester
– 5-digit LCD meter with engineering unit
– Stainless steel electronics housing
– Wide selection of anticorrosion materials
