PT40-4000psig-2-1-45-70-ST8-CC

Pressure Sensors Transducers Overview

The NOSHOK PT40-4000psig-2-1-45-70-ST8-CC is a high-accuracy fixed-range pressure transmitter with a gauge range of 0 to 4000 psig. It features a 4mA to 20mA, 2-wire output signal and operates on a power requirement of 10V DC to 35V DC. The device offers ±0.25% of span accuracy with non-linearity defined by the best fit straight line per IEC 61298-2 at reference conditions. It has a response time of less than 1ms between 10% and 90% full scale. The wetted parts are constructed from 316 stainless steel. Environmental ratings include IP65 for DIN EN 175301-803 Form C and A connectors, and IP67 for bayonet or conduit options.

Pressure Sensors Transducers Procurement Notes

Verify the specific ordering suffixes against the official NOSHOK datasheet to ensure the selected configuration matches the required process connection, electrical output, and environmental rating. Confirm that the 4mA to 20mA two-wire interface aligns with your system's loop requirements. Check for any special packaging or handling instructions if the application involves sensitive instrumentation environments. Ensure compatibility with the specified power supply voltage range of 10V DC to 35V DC before finalizing the purchase order.

Pressure Sensors Transducers Selection Notes

Select this model when high accuracy and fast response are critical for pressure monitoring in industrial settings. The 4000 psig range suits medium-to-high pressure applications where standard transmitters may lack precision. Consider the field-adjustable offset and span features for easy calibration without removing the unit. The IP65/IP67 ratings make it suitable for harsh environments requiring protection against dust and water ingress. Evaluate the 316 stainless steel construction for corrosion resistance in various media.
