Explosion Proof Pressure & Temperature Transmitter

AST46PT

AST46PT Explosion Proof Pressure and Temperature Transmitters in Factory Sealed Configuration

AST46PT high accuracy Explosion-proof Pressure/Temperature 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
Applying digital compensation, this product offers top performance over hot and extremely cold temperatures. Having pressure and temperature at the same device can add safety and greater accuracy to overall system design at the fraction of the cost of an additional transmitter.
