Overview
AVKP19 piezoresistive liquid level transmitter is an explosion-proof product developed based on the special needs of liquid level measurement and control sites. It uses stainless steel corrugated hose design to protect cables and a dedicated amplification and adjustment circuit, which can effectively solve corrosive liquid media, open tank liquid level measurement, and provide multiple output signals.
AVKP19 explosion-proof liquid level transmitter adopts a split input structure, and the liquid input is an OEM pressure sensor with isolation, which has high accuracy and good stability; The external explosion-proof junction box or explosion-proof instrument housing is the circuit output part, with built-in wiring terminals for convenient and fast operation; The product can be installed in various ways such as input type, plug-in thread, and flat flange; The protection level of the front-end sensor of the transmitter is IP68.
The AVKP19 explosion-proof liquid level transmitter has small size, light weight, and good long-term stability. The product is strictly manufactured in accordance with the ISO9001 international quality assurance system. Applied to the measurement of various liquid media compatible with stainless steel, suitable for liquid level measurement in fields such as petroleum, chemical medicine, metallurgy, power plants, mines, industrial sewage treatment, urban water supply and drainage, hydrological exploration, etc.
This product is an explosion-proof liquid level transmitter that complies with GB 3836.1-2010 and GB 3836.4-2010 standards. The explosion-proof label is Ex db IIC T6 Gb and is suitable for general explosive gas environment conditions. And it has been reviewed and qualified by the National Quality Supervision, Inspection and Testing Center for Explosion proof Electrical Products.
