Explosion Proof Pressure & Temperature Transmitter | Factory Sealed Gauge | ASIC

AST46PT-Factory-Sealed

AST46PT high accuracy Explosionproof 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. Utilizing Krystal Bond Technology™, the sensing element will measure pressure in the most extreme temperature conditions. Where other sensor technologies will freeze or boil, the AST46PT uses a one piece stainless steel sensor to offer continuous operation.

Benefits

- Krystal Bond™ Technology
- ANSI 12.27.01-2003 Single Seal Approved
- Pressure and Temperature Output from One Device
- ASIC Compensation
- Superb Temperature Performance
- Excellent Accuracy
- High Proof and Burst Pressure
- From 100 to 20,000 PSI (Factory Sealed Gauge)*
- Available in Exotic Alloys (Consult Factory for Inconel 718 or Hastelloy C276)

*For pressures less than 100 PSI, see AST46PT Vented Gauge Pressure data sheet.

Applications

- Well Optimization
- Oil and Gas Pipelines
- Drilling Platforms
- Marine & Offshore
- CNG / Hydrogen Fill Stations
- Paint Booths
- Remote Telemetry Unit
- Cold Climate Drilling & Mining
-

**For units with loop-powered 4-20mA output, the pressure loop must be powered or the temperature output will not operate.

¹ Accuracy includes: Non-linearity, Hysteresis and Non-repeatability
