5 VDC OUTPUT PRESSURE TRANSDUCER ETM/ETL-422(X)-375 (M) SERIES

Product catalog summary
Overview: The ETM/ETL-422(X)-375 series is a miniature threaded pressure transducer designed for aerospace applications. It features a 5 VDC output, hybrid microelectronic regulator-amplifier, and all-welded construction with a hermetically sealed package.
Specifications:
  • Output: 5 VDC
  • Electrical Excitation: 18 to 36 VDC
  • Maximum Current: 25 mA
  • Output Impedance: 200 Ohms (Max.)
  • Pressure Range: 1.7 to 350 BAR (25 to 5000 PSI)
  • Over Pressure: 2 times rated pressure, max 30000 PSI (2100 BAR)
  • Burst Pressure: 3 times rated pressure, max 35000 PSI (2400 BAR)
  • Operating Temperature: -65°F to +275°F (-55°C to +135°C)
  • Compensated Temperature: -65°F to +250°F (-55°C to +120°C)
  • Total Error Band: ±2% FSO at 32°F to 180°F, increasing to ±3% at other temperatures
Design and Construction: The transducer utilizes a flush metal diaphragm and a solid-state piezoresistive sensing element protected by a metal screen. It is welded to a stainless steel body, ensuring stability and reliability. The design incorporates Kulite's patented leadless technology and a proprietary electronics module for operation from an unregulated power supply.

5 VDC OUTPUT PRESSURE TRANSDUCER ETM/ETL-422(X)-375 (M) SERIES-1

ETM/ETL-422(X)-375 (M) SERIES • 5 VDC Output • Hybrid Microelectronic Regulator-Amplifier • All Welded Construction • Hermetic Sealed Package • Aerospace Quality Components • "X" Identifies Electrical Connection Option • Thermorad Jacket Compatible With Most Aircraft Fluids • Patented Leadless Technology VIS® (ETL Series) • Intrinsically Safe Applications Available(i.e. IS-ETM-422(X)-375) The ETM/ETL-422(X)-375 is a miniature threaded pressure transducer. The hexagonal head and o-ring seal make it easy to mount and simple to apply. The ETM-422(X)-375 utilizes a flush metal diaphragm as a force collector. A solid state piezoresistive sensing element is located immediately behind this metal diaphragm which is protected by a metal screen. Force transfer is accomplished via an intervening film of non-compressible silicone oil. This sensing sub assembly is welded to a stainless steel body. The ETL-422(X)-375 utilizes Kulite's Patented Leadless Technology. A solid state piezoresistive sensing element is protected by a metal screen. This sensing sub assembly is welded to a stainless steel body. Note: Custom pressure ranges, accuracies and mechanical configurations available. Dimensions are in inches. Dimensions in parenthesis are in millimeters. All dimensions nominal. (N) Continuous development and refinement of our products may result in specification changes without notice.
