Explosion Proof, Heavy Duty Pressure Transducer


Made For Harsh Conditions & Hazardous Locations

The PT-405 pressure transducer offers high accuracy and reliability over a wide range of pressures with cCSAus approvals.


The PT-405 is built to handle your heavy duty applications: high pressures, hazardous locations, high vibration, and moisture.

Hazardous Location Certification
The PT-405 has Class I, Div 1, Explosion Proof certification from CSA, and single seal construction for the highest safety factor.

Durable Construction
Not only is the PT-405 explosion proof, it is built tough to survive in harsh environments, high vibration, high-pressure spikes, and even extended temperature compensation.

Tank Cloud Compatible
With Modbus output, the PT-405 can be monitored or controlled online through Tank Cloud.

Calibration Services

NIST Certificates and Re-Calibration

While ordering your PT-405 pressure transducer, or any of our pressure sensors or gauges, request a NIST certificate for either 0.25% or 0.1% accuracy. We offer the same service on your regular factory re-calibration, which we recommend having done annually.

Send your pressure transducer back in for a factory re-calibration on a regular basis. This will ensure accuracy and reliability for years.
