Hansen VLT-04NX, Techni-Level Probe, 4-20 MA

Hansen Techni-Level level transducer probes have fast become the industry standard for liquid refrigerant level control and monitoring. These reliable, well engineered electronic level transducer probes, when properly used, operate trouble-free and are not affected by reasonable changes in refrigerant temperature or pressure. They provide a computer compatible 4-20 mA (milliamp) output signal proportional to liquid level. Probes consist of a compact, electronic transmitter in a watertight housing assembled on top of a rugged, capacitance type level sensor. Probe active lengths up to 168" (427 mm) are available. Normally, the probe must be inside a level column. Typical applications include: vertical and horizontal vessels, pump accumulators, pilot receivers, and refrigerant loss monitoring. These probes are operating control devices and should never be used as safety devices.

Note: WLT is a direct replacement for all VLT models.

The WLT-C is used to directly control an MCV without the need for a controller.
