Product Description
The transmitters adopted silicon diffusion sensor, ceramic piezoresistive sensor or ceramic capacitive sensor, by using piezoresistive effect and Wheatstone bridge principle and pressure change capacitive principle to achieve accurate measurement of pressure in certain depth. It has the advantages of high reliability and good stability.
The HB872 modle has full metal structure, suitable for measuring the oil level of open tank and floating roof tank.
HB872D is a derived type level transmitter that has the "Intrinsica safety" performance, could intall in the "O" zone, mainly using for the measurement of oil level in the oil tank of hydropower plant. The features of this meter are small measurement range with high stability, not affected by the change of liquid level. Specification| Range | 0-200m(see model and order code) |
