Model Z

The Model Z pressure transducers are sensors manufactured out of 17-4 PH stainless steel, wetted material for ranges up to 2,000 psi, 15-5 PH stainless steel, wetted material for ranges 2,000 psi and greater. These pressure transducers are built for rugged, industrial applications that require high accuracy and measurement stability. Pressure ranges span from 0.5 psi to 60,000 psi. They utilize complete four-arm 350 ohm strain gauge bridges.

The Model Z is available with a variety of options for extended temperature operation, electrical terminations, wetted material and high-level outputs including 5 Vdc or 10 Vdc and 4 mA to 20 mA. Most high-level output models have internal shunt calibration circuits as a standard feature to allow easy setup of the sensor to the data system. An optional internal signature calibration chip provides calibration information for automatic setup with the Model SC four-or-twelve channel digital indicator.

The Model Z is a strain gauge-based transducer. This design references the primary pressure sensing diaphragm to the atmosphere and provides a stable zero regardless of the transducer environment. The absolute Model Z has an all-welded, vacuum reference chamber ensuring long-term stability.
