Z Mid range wet/wet differential pressure transducer

High accuracy differential pressure measurement for liquid media in demanding industrial environments. Designed for engineers who need reliable wet/wet performance with flexible output options and robust stainless steel construction.


Key features

  • 0.25% full scale accuracy
  • 50 to 750 psid ranges
  • Bi-directional measurement
  • Stainless steel construction
  • mV/V, 4–20 mA or voltage output
  • Intrinsically safe option available

Performance highlights

The Z mid range wet/wet differential pressure transducer is designed for precise differential pressure measurement in liquid media. With an accuracy of ±0.25% full scale and ranges from 50 to 750 psid, it delivers stable and repeatable performance in industrial process environments.

The bonded foil strain gauge technology ensures high linearity and minimal hysteresis, making it suitable for both test and permanent installation setups.

Usage conditions

This differential pressure transducer is built with a stainless steel housing and wetted parts, enabling reliable operation in demanding industrial environments. It supports line pressures up to 1500 psi and offers overload protection for enhanced durability.

Temperature compensated ranges and optional internal amplifiers allow flexible integration into existing control and monitoring systems.

Possible applications

  • Hydraulic system monitoring
  • Industrial process control
  • Pump performance testing
  • Filter monitoring
  • Fluid power systems
  • Test benches for liquid systems

Advantages of choosing this product

Engineers benefit from a rugged design combined with flexible electrical outputs including mV/V, 4–20 mA, 0–5 Vdc, and 0–10 Vdc. The optional intrinsically safe configuration makes it suitable for hazardous environments.

Removable pressure adaptors and multiple port configurations simplify installation and maintenance.

Other important features

  • Bonded foil strain gauge technology
  • CE approved
  • Optional internal signal conditioning
