DESCRIPTION

The 3100/3200 Series high-pressure OEM transducers feature a sputtered thin-lm sensor to provide high levels of performance and stability for large volume OEM installations. A wide choice of outputs as well as electrical and pressure connections means that the unit is suitable for most applications without modication. In addition, the compact construction of the 3100/3200 Series makes it ideal for installations where space is at a premium.

The Model 3200 features a thicker diaphragm and a restrictor (optional) to handle environments where extreme positive or negative pressure spikes are a concern. Proof pressures on the Model 3200 are 3x full scale on 50 psi up to 10,000 psi pressure ranges.

PRINCIPLE OF OPERATION

Sputtered Thin Film Strain Gauge Pressure Sensors Using the well proven Wheatstone Bridge principle, molecular layers are sputtered onto a 17-4 PH stainless steel diaphragm and the circuit is etched to provide excellent resistor denition and uniformity. Sputtered thin lm technology allows the design of simple, highly accurate and compact strain gauges deposited onto the back of the sensing diaphragm, which is in direct contact with the media. This method virtually eliminates drift, while oering enhanced sensitivity.

GENERAL PURPOSE/OEM

PRESSURE CAPABILITY

Application pressure should be restricted to the rated-range of the transducer. The maximum overpressure is the pressure limit at which the transducer will not show signicant oset shift. The minimum burst pressure is the test-rating for uid containment.

The data in the tables is “times rate ranges” (xRR).
