Reliable Draft Measurement for Industrial Environments

With an accuracy of A1% of full scale and a rapid response time of less than one second, the PU-PI pressure transmitter delivers precise real-time monitoring of low air or draft pressure. Its robust construction and shock-resistant housing make it suitable for harsh industrial applications, while its powder-coated finish ensures added durability.


User-Friendly Operation and Installation

This transmitter is designed for ease of use. External zero adjustment allows quick recalibration without opening the case. The analog display offers clear readings, with a laser-engraved scale resistant to wear. Installation is straightforward thanks to the supplied mounting bracket and standard 1/2 BSP threaded connection.

FAQ's of Draft pressure transmitter PU-PI:


Q: How do I install the Draft Pressure Transmitter PU-PI?

A: The transmitter is designed for easy installation using the supplied mounting bracket and a standard 1/2 BSP bottom connection. Ensure the unit is securely mounted in a location where ambient temperatures do not exceed the -10C to +60C operating range.

Q: What media can I use with this pressure transmitter?

A: The PU-PI transmitter measures draft and low air pressure specifically in air and flue gas applications, making it ideal for industrial ventilation and combustion systems.

Q: When should I perform zero adjustment, and how is it done?

A: External zero adjustment should be performed if you notice drift in the baseline reading or after significant maintenance. Adjustment is done easily from outside the case without disassembly for maximum convenience.

Q: Where can this transmitter be used considering its ingress protection and material?

A: Rated at IP54, the transmitter can be used in industrial indoor environments exposed to dust and light water splashes. Its powder-coated mild steel casing and shock-resistant design provide durability in harsh conditions.

Q: What is the benefit of factory calibration for this transmitter?

A: Factory calibration ensures reliable and accurate measurements right out of the box, saving time and minimizing setup errors for users in fast-paced industrial environments.

Q: How fast does the transmitter respond to pressure changes?

A: The PU-PI responds in under one second, making it suitable for monitoring dynamic draft or low air pressure changes in real-time process applications.
