hazardous Materials/Explosion Zones






It can be challenging and costly to install equipment in hazardous/explosion zone environments. Fortunately, there are effective solutions that employ inherently safe pneumatic components within these critical areas. We offer proven, reliable liquid level tank sensors that do no require electronic components at the tank and transmit a pneumatic output signal.

Installed cost using pneumatic components can be attractively low and provides extremely long service life. Pressure-based systems are perhaps the most simple and reliable technology for measuring level.

King offers complete process control and inventory management solutions. Sensor selection includes a variety of configurations and materials for total compatibility. We provide accurate and reliable systems designed to function in harsh and demanding environments.

purge780-thumb Purge Control - When purged with compressed air, liquid within the downpipe is displaced by air pressure equal to the hydrostatic force of liquid in the tank.

telesensor-thumb TeleSensor detects level by sensing hydrostatic pressure created by liquid depth. Acting on the force balance principle, a sensitive diaphragm is exposed to the liquid contents of the tank.
