Explosion Proof Pressure Transmitters
Class I Div 1 - Sealed Gauge

AST4600-Factory-Sealed

AST4600 Class 1 Div 1 Explosion-Proof Pressure Transmitter

AST4600 Explosionproof Pressure Transducer / Transmitter is CSA approved for use in hazardous areas including:

  • CSA 30 (UL1203/FM3615) Class 1 Zone 1
    Group IIC
  • CSA 30 Class 1 Div 1 Groups A, B, C, D Explosionproof
  • CSA 30 Class 2 Div 1 Groups E, F, G Dust Ignition-proof
Constructed with a simple-yet-rugged design, the factory-sealed AST4600 stands up to a variety of Explosionproof applications where price and performance are critical.

Available with voltage output signals, the AST4600 can be used for applications requiring low power consumption or packaged with a 4-20mA output signal for common integration into PLC's and controllers and long distance transmissions.

This pressure transducer features AST's Krystal Bond™ Technology, a one-piece stainless steel sensing element that provides high proof and burst pressure capability, long-term stability, and repeatable readings. The sensor is most commonly packaged with 316L Stainless steel to offer excellent media compatibility and comply to NACE MR0175 standards.
