overview

SN1161 pressure type liquid level transmitter is a product developed for liquid level measurement in special situations such as high temperature and strong corrosion. The sensor and amplification circuit of this product are located on the upper part of the pressure tube, and the liquid static pressure is transmitted to the sensor through the air in the gas collection cylinder inside the liquid. A high-performance pressure sensing chip is used to avoid direct contact between the sensor and the medium.

characteristic

◆ All stainless steel or PP welded structure
The sensor does not come into contact with the measured medium, ensuring high reliability
◆ Equipped with reverse connection protection and overcurrent protection
◆ Diffuse silicon core, resistant to vibration and impact
ASC dedicated integrated circuit, DSP digital conditioning algorithm, good linearity
◆ Low temperature drift, high speed, anti-interference, suitable for high temperature environments
◆ IP68 protection, explosion-proof, anti-corrosion, lightning strike resistant
◆ Easy installation and maintenance
