Product Description

Temperature and LiquidLevel Transmitter Sensor For Hydrologic Monitoring, Constant Pressure Water Supply

L040T line is the transmitter applicable for measuring the temperature and pressure at the same time. Featuring high reliability, stability and accuracy, the product is widely used for the measurements of gas and liquid, such as water, oil and light corrosive liquid and gas. This product line adopts 1Cr18Ni9Ti stainless steel construction, diffused silicon-based sensor of international brands, and the specially designed V/I converting circuit. It is easy to perform zero/span trim. Based on the locations, different high-strength breathable cables featuring wear-proof, acid/alkali resistance and oil resistance can be configured.
