Series 634ES Transmitters sense a single pressure for air, compatible gas or liquid and provide 4-20 mA output signal. Positive pressure can be measured within an accuracy of ±0.5% of span. The Series 634ES uses an isolated piezoresistive pressure sensor to produce a resistance change across a wheatstone bridge. Convenient 2-wire operation simplifies installation. Zero and span adjustments are fully protected inside a rugged die cast aluminum housing with durable gray polyurethane finish. Enclosure is designed to meet NEMA 4X requirements.

Environment - The Series 681 Transmitter is designed to be used with any gas or liquid compatible with 316L stainless steel (316 for ranges > 30 psig).  It is designed to be splash and drip proof for wash-down cleaning and can also be completely submerged with the exception of the open end of the electrical cable. Cleaning - The pressure sensing diaphragm will withstand normal high pressure washing and partial vacuums created by fast cooling of steam sterilized tanks.  However, be sure not to exceed the proof pressure (listed on specification sheet).  In high pressure washing, care should be taken not to spray directly on diaphragm as it could result in exceeding the proof pressure.  The 681 can also be cleaned by dipping the diaphragm in a container of cleaning solution or by wiping gently with a soft cloth.
Temperature Limits - The operating temperature limits of the 681, based on the limits of the electronics, are -40F to 260 F. F to 180 F range Thermal Effects20

40. Dwyer pressure transmitter Series DPT Digital Pressure Transmitter
The Series DPT Digital Pressure Transmitter with Switches combines a large, 14-segment LED display with two programmable solid state switches into one compact unit. A unique, 3-way rotating design allows the DPT to meet specific installation requirements without any retrofitting. The display and electrical connection can be rotated independently to maximize visibility while still orienting the electrical connection in the best position for the cable connector. Large, ergonomically designed push buttons allow for quick/easy programming and thin-film piezoresistive sensor technology guarantees long-term reliability and stability.
The Series FDT Flush Diaphragm Transmitter is designed for highly cyclical conditions. Flush sensor feature prevents any potential inaccuracies due to build-up or blockage which is a typical problem found in most non-flush transmitter sensors. Units have a non-oil filled sensor element that provides resistance to temperature fluctuations. Manufactured from a solid piece of steel, the sensing diaphragm can withstand the most abrasive/cyclical applications. Series FDT transmitters perform well in high cyclical environments with the presence of water-hammering or spiking.
Flush feature greatly reduces chance of leakage. Tough materials allow the unit to withstand harsh process conditions. Advanced manufacturing techniques, extreme environmental burn-in, and thorough residual stress relieving procedures ensure unit will maintain its high performance standard over time.

Dwyer pressure transmitter series IS626 Intrinsically safe pressure transmitter
The Series TPT Pressure Transmitter is the ideal choice for all types of industrial pressure applications. Machined from a solid piece of 17-4PH SS, the TPT provides a leak proof, all metal system without O-rings, welds, or organics exposed to the pressure media. Its design allows for stable operation when subject to shock and vibration. Utilizing piezoresistive technology with digital compensation and temperature correction, the TPT gives high accuracy and stability under harsh environmental conditions. Available in ratiometric and 4 to 20 mA outputs.

TPT-R01 Industrial pressure transmitter, 0-100 psi, ratiometric.
TPT-R02 Industrial pressure transmitter, 0-250 psi, radiometric.
