Explosion Proof Transmitter | Pressure and Temperature Outputs

AST46PT-Vented

AST46PT high accuracy Explosionproof Combined 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

Applying digital compensation, this product offers top performance over a wide temperature range. 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.

Design Benefits

- ANSI/ISA - 12.27.01.2003 Certified "Single Seal" (no need for expensive secondary seal)
- Pressure and Temperature Output from One Device
- ASIC Compensation
- Superb Temperature Performance
- Wide Operating Temperature Range
- Excellent Accuracy
- High Proof and Burst Pressure
- From 1 to 1,000 PSI Gauge*
- Available in Exotic Alloys (Consult Factory for Inconel 718 or Hastelloy C276)

*For pressures over 1000 PSI, see AST46PT Factory Sealed Gauge data sheet.

Applications / Industries

- Well Optimization
- Oil and Gas Pipelines
- Drilling Platforms
- Panel Instrumentation
- 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
