Product Description

HPM420-T Gas collection cylinder type high temperature resistant immersion level transmitter consists of a stainless-steel gas cylinder, a stainless-steel capillary and a junction box. The sensor and signal processing circuit are designed inside the junction box, and the gas cylinder is put into the liquid to be measured to collect pressure signals. The liquid level pressure signal collected by the gas in the gas cylinder transmits the pressure to the sensor through the stainless-steel capillary, thereby avoiding direct contact between the sensor and the measured medium, and is suitable for high temperature corrosive occasions, effectively solving the problem of high temperature corrosive liquid and sewage level measurement.

Product Features

1. Gas collection cylinder type liquid level probe
2. Probe immersion measurement method, simple and convenient installation
3. Can measure high temperature media
4. Full metal armor, high-strength steel pipe structure
5. On-site display optional
6. Lightning protection optional
