HPT701 2025

Product catalog summary

Applications
The HPT701 is a standard industrial air differential pressure transmitter suitable for various applications including HVAC air differential pressure, wind pipe pressure measurement, wind machines, industrial dust removal equipment, purification plants, blow down expanders, and leak detection devices.

Features
This device is pressure sensitive, offers digital temperature compensation, and is assembled with imported chips. It is designed to be strong against humidity and water, with an IP65 enclosure. The transmitter features advanced circuit linearity, is compact, and easy to install.

Specifications
The HPT701 operates within a pressure range of 0-100Pa to 200KPa, with an accuracy of 0.5% F.S typical, and 0.25% F.S optional. It functions in temperatures from -10℃ to 80℃ and is compatible with dry and non-corrosive gases. The device supports various electrical outputs including 4-20mA, 0-5V, 0-10V, 0.5-4.5V, and RS485 Modbus RTU, with a power supply range of 8-30V or 24-30V without a potentiometer.

Installation
The transmitter is easy to install with M4 screw mounting holes and threaded air nozzles. It can be fixed using screws or M10×1.5 nuts.

Ordering Information
Users can select the pressure range and unit from a provided table. The part number selection includes options for pressure range, unit, signal output, power supply, pressure connection, maximum static pressure, accuracy, and cable length.

Accessories
Optional accessories include a liquid level display control device, an adapter converter for RS-232 to RS-485 signal conversion, and a terminal box with IP67 rating for moisture-free electrical termination.
