Explosion-proof Liquid 20mA NYCSUL-503 Ultrasonic Level Switch connected with Thread
NYCSUL-503 Ultrasonic Level Switch Working Principle
The MPM426WPC level transmitter is a fully welded, submersible level measurement device. It uses a piezoresistive OEM pressure sensor with proven long-term stability and reliability, and a special digital compensation circuit that are built into a stainless steel housing. The integrated structure and standardized output signal make it easy for the on-site use and automatic control. The vented Teflon® jacketed cable and the housing are hermetically sealed, which can be used in the liquids that are compatible with the sensor material for a long time.
The change of the level is determined according to the time difference from ultrasonic re transmission to re reception and the known sound speed. The electronic device processes the microwave signal and finally converts it into an electrical signal related to the level.
NYCSUL-503 Ultrasonic Level Switch Design Feature
1. The upper and lower limit settings and alarm settings at any point can be used for continuous liquid measurement and liquid level control.
2. Short circuit and reverse polarity protection.
3. Automatic production line ensures high quality and stability.
4. High reliability, safe and easy to use.
