NOSHOK PTI40 Premier Accuracy Intelligent Pressure Transmitter

The NOSHOK PTI40 Series Intelligent Pressure Transmitter is specifically designed with differential pressure readings in mind. The PTI40 utilizes a piezoresistive silicon sensor for use in general industrial applications where improved accuracy and temperature compensation is required. When the PTI40’s sensor element is put under pressure, it creates a deflection in the silicon substrate and bridge network. This generates a value that is converted into a pressure measurement within 0.075% accuracy, providing consistent, exact readings in less than 200ms of change occurring. 

The PTI40 features a compact but durable design, with a stainless steel flush diaphragm that reduces the fill fluid required, as well as the potential for damage when utilized in harsh environmental conditions. The design features easy-to-implement adjustments to all available ranges via a streamlined 1 button joystick on the PTI40’s display, or through the HART output.

All NOSHOK PTI Series Transmitters come with a three year warranty.
