Product Description

High-corrosivenessResistant Liquid Level Transmitter for chemistry experiments

L044/45 line is liquid level transmitter of high accuracy, reliability and stability. With the sensing element of ceramics, the product is used for the measurements of corrosive liquid and gas. This product line features the housing of titanium alloy and PTFE, ceramics sensing element of international brands, and the specially designed V/I converting amplifier 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. non-polarized two-wire output and DC-AC three-wire output.
