    The Series 700 family of submersible pressure transducers is specifically designed to meet the rigorous environments encountered in liquid level measurement and control. It can be configured to perform to specifications under the most adverse, reactive conditions.

    These transducers incorporate the latest advancements in piezoresistive pressure sensing technology. A stability-enhancing charged "Field Shield" is vapor deposited directly to the pressure cell. A welded 316 Stainless Steel diaphragm, with a spring rate ratio of 1000:1 with the piezoresistive pressure cell, is used for contact with the media. The transducer housing is an all-welded design, constructed of corrosion resistant 316 SST. Titanium housing with hastelloy/platinum sensor combination is offered for extremely corrosive media.

    The Series 700 also features state-of-the-art, surface mount internal signal conditioning which provides a power supply rejection of 0.001% and either a 4-20 mAdc, 0-5 Vdc, or mVdc process signal. Approvals to FM, CSA, and UL are available for Class I, Div 1, Groups A, B, C and D, and Class II, Div 1, Groups E, F and G, and Class III, Div 1 hazardous locations. These instruments also meet CE approval according to EN-50081-2 and EN-50082-2. Hazardous locations installation must be to local and national electrical codes and installed with an approved electrical barrier, such as manufactured by R.G. Stahl, Inc.

    Each transducer is shipped with a barrier that prevents moisture from entering the cable vent tube and with a traceable calibration card. The card specifies input/output conditions and actual data recorded during manufacture. Optional calibration is available when additional performance characteristics are required. All units are repairable and have low power requirements.
