ZRN701B Split Level Transmitter

bargain

A Product description:

ZRN701B series HIP Level Transmitter Is based on the hydrostatic liquid height measured proportional principle, piezoresistive effect using foreign advanced isolated diffused silicon sensing element, the static pressure is converted to an electrical signal, and then after temperature compensation and linearity correction, converted to Standard electrical signal (usually 4 ~ 20mA), this input level meter hydrostatic Common type and field-type liquid crystal display two.

ZRN701B series HIP Level Transmitter Used in petrochemical, metallurgical, power, pharmaceuticals, water supply and drainage, environmental protection systems, and liquid level measurement in various media industries. Compact structure, easy set-up and installation flexibility for users to easily use more convenient. 4 ~ 20mA, 0 ~ 5v, 0 ~ 10mA standard signal output, etc., optionally by the user as needed.
