VDC Wiring:
Connect a 3 wire VDC output transducer to a typical power supply and the voltmeter, connect the -
terminal of the power supply to the - input terminal of the meter with a length of 22 AWG or heavier
wire. Connect the - excitation (black) lead of the transducer to the - input terminal of the meter.
Connect the + input terminal of the meter to the signal lead (white) of the transducer. Connect the +
terminal of the power supply to the + lead (red) of the transducer. Connect the drain wire to a good
earth ground. (See
Appendix A

.)
Protective Cage Diaphragm Protector:
The MEAS LTB comes standard with a field removable diaphragm protector (one-inch or 25 mm
standoff). The protective cage diaphragm protector can easily be taken off by removing six (6)
fasteners located on the bottom of the unit.
Position Sensitivity:
The transducer should be installed so that the diaphragm located behind the nose cap is oriented in a
vertical position, otherwise the unit could exhibit an offset.
General Maintenance Tips for Submersible Transducers:
Desiccant Maintenance
WARNING: POTENTIAL ELECTROSTATIC CHARGING HAZARD
In hazardous locations:
●
Avoid building up static charge on case of data protector and plastic accessories.
●
Use damp rag to wipe data protector and plastic accessories to avoid static build
up.
If you use a desiccant vent filter, you should establish a regular maintenance schedule. You should
change your vent filter when it is 75% spent (pink color). Replacement filters are available at a
nominal cost from the factory. Do not remove the old vent filter until a new one is available.
Remember that Measurement Specialties’ improved 810 SuperDry™ Vent Filter is designed to be
effective for at least one year before requiring replacement.
