INTRODUCTION
Hansen Level Transducer Sensors are reliable, well
engineered electronic level monitoring devices.
provide a computer compatible 4-20 mA (milliamp) output
signal proportional to liquid level. The sensor consists
of a compact, electronic transmitter in a watertight
housing assembled on top of a rugged mechanical
base. The wire element is an insulated stainless-steel
wire and can be mounted directly in a level column. If
it needs to be installed in a vessel, then an inner pipe
is required.
Typical applications include: vertical
vessels, pilot receivers and pump accumulators. These
sensors are intended to be operating control device
should never be used as safety devices. The sensor
can be installed in refrigeration systems and similar
demanding applications with high pressure fluids.
All versions emit a 4-20mA analog signal via the M12
connector and field cable.
There are two different versions of transducer sensors.
WLT: 2-wire Level Transducer Sensor
WLT-C: 3-wire Level Transducer Sensor with
integrated Motorized Valve (MCV) controller.
This bulletin will cover the WLT-C which can be
used for new installations, and direct VLT + PXVC-L
replacement for MCV control. For the quick start
