●Liquid Level Pressure Transmitter/Transducer with Display Overview

The measurement of water or liquid level using hydrostatic equilibrium system is an important application of pressure sensors. The high–sensitivity silicon piezoresistive sensitive element fabricated with micromachining technology is the critical component of the liquid level transducer, supported with the special cable provided with an air tube as well as special water-tightness technology, which not only ensures the water tightness of immersion transducers, but also makes the reference pressure chamber connect with the ambient atmosphere, so as to attain accurate measurement results and excellent stability.

Tips for Type Selection
1. The medium to be measured shall be compatible with the material contacting with the product. Meanwhile, the density of the medium to be measured during measurement shall be indicated (except for water).
2. As an additional function code for type selection, the code “E” for intrinsically safe explosion-proof type Ex ia II CT5 denotes that power source must be supplied via safety barrier.
3. The length of cable shall be L = X m + 1m. Please indicate any extension (if needed) when placing an order.
4. To install the product in thunderous areas, select HM21F Anti-lightning Liquid Level Transducer when placing an order.
5. The corresponding relationship of 1m water columns with pressure under standard conditions ( i.e. 4℃, g = 9.80665 m / s2):1mH2O=0.1kgf/cm2(Kgf  /cm2 )=9.8kPa(KPa)
6. For other special requirements, please discuss with us and clearly indicate them in the order.
