DS & WT SERIES PRESSURE TRANSDUCERS ♦ Wide pressure ranges available Adjustable zero and span Available with voltage or current outputs Rugged anodized aluminum housing Stainless steel sensor option DS series pressure transducers accurately measure pressure of gases or fluids. The output is an electrical signal based on the measurement. Conditioning of the electrical signal from the strain gauge sensor gives either 0-10 VDC or 4-20 mA output depending on the model ordered (consult factory for other available outputs). The electrical output is a linear ratio of the pressure sensed. DS series transducers are enclosed in a rugged aluminum housing. A strain relief protects the wiring from damage caused by excessive pulling force. The standard version (DS) measures pressure using a piezoresistive semiconductor sensor chip. The stainless steel version (DST) utilizes the same silicon etched device mounted on a stainless steel diaphragm. On these units, no elastomers or o-rings contact the pressurized media. All media wetted parts are ANSI type 316L stainless steel. The NEMA4 version (WT series) is electrically identical to the DS series. The WT series is housed in a slightly larger canister that is sealed against fluid spray from any direction. ELECTRICAL CONNECTOR— USER SPECIFIED

CALIBRATION PROCEDURE ELECTRICAL CONNECTION The WT, DS & DST series pressure transducers are factory calibrated. Should further calibration be required, please follow these procedures. Two calibration potentiometers on the pressure transducer set the overall zero and span points. They are located on the back of the transducer recessed in two holes.¹ (See figure 1 for location) These adjustments are set by the factory and covered with metallic tape. This metal tape may be removed to recalibrate the unit.¹ Figure 1 *You must have a good understanding of what the span and zero set adjustments do...
