Hersman Pressure Transmitter

Hirschmann pressure transmitters are high-precision industrial instruments specifically designed for accurate pressure measurement in harsh environments. It features a robust and durable stainless steel casing and advanced sensing technology, ensuring reliable performance in applications including process control, HVAC, hydraulics and oil/gas systems. This device offers a wide measurement range (customizable from 0 to 1000 bar), an accuracy of ±0.25%, and is compatible with liquids, gases or vapors. It features multiple output options (4-20mA, HART, Modbus) and IP67/Ex certification for hazardous areas. With powerful temperature compensation (-40°C to 125°C) and long-term stability, Hersman transmitters can minimize downtime while providing real-time data to optimize operational efficiency. It is easy to install and has low maintenance costs, making it an economical and efficient critical pressure monitoring solution.

Product Features

1. High precision and stability

Laser drag trimming and temperature compensation technology are adopted to reduce the influence of temperature drift (such as temperature drift ≤±0.02%FS/℃).

2. Corrosion resistance and impact resistance

The material of the liquid-contact part is stainless steel 316L, ceramic or PTFE coating, suitable for corrosive media.

It can withstand an impact of up to 100g and vibration of up to 20g (20-5000Hz).

3. Easy to install

It can be directly installed on the pipeline and supports various threaded interfaces such as M20×1.5 and G1/2 ", without the need for additional brackets.

4. Diversified output and customization

It supports customized signal output (such as three-wire voltage or RS485), and the pressure interface and electrical connection can be flexibly configured.

5. Explosion-proof and protective design

The explosion-proof model is suitable for hazardous environments and is compatible with IP65/IP67 protection levels
