U.S. GAUGE PMT PRODUCTS PRESSURE TRANSMITTERS BULLETIN DB-831LP PART #K796395 Model 831 Low Power Fixed Range Pressure Transmitter F E AT U R E S A miniature, low-priced fixed range transmitter, just 0.83 lbs. (374 grams) All welded 316 stainless steel construction and wetted parts (no aluminum) Ranges from 0-15 to 0-5000 PSIG (0-1 to 0-345 bar) +0.30% accuracy Designed to meet FM Explosion-proof approvals (Consult factory for approvals) 8 VDC power operation, 1 to 5 VDC output 6 VDC power operation, 0.8 to 3.2 VDC output 3/4" NPT Female conduit connection cable 1/2" NPT Female pressure port connection Straight in-line construction for a slim profile 24 inch cable standard DESCRIPTION The AMETEK Model 831 low power pressure transmitter represents a natural extension of the Model 831 fixed range transmitter. An all stainless steel transmitter, it is designed for years of stable per-formance in even the toughest environmental and media conditions. This Model 831 has been designed to meet FM explosion-proof ratings and also meets NACE standards for offshore applications. A one year warranty is standard with every unit. The small size and light weight of the Model 831 transmitter eliminates the need for complicated mounting hardware and mechanical supports, thereby reducing installation time substantially. The in-line connection permits simple field wiring without the need for additional hardware, adding to the speed and ease of installation. EFFECTIVE: 12/98 It provides a three wire 1-5 or 0.8-3.2 voltage output and requires less than 30 milliwatts of total power to operate. The combination of low power requirement, small size, excellent performance and low price make the Model 831 low power transmitter ideal for critical outdoor, solar/battery powered applications. The Model 831 low power transmitter requires 6 or 8-14VDC excitation and is available in pressure ranges from 15 to 5000 PSI. PMT Quality Commitment AMETEK's commitment to quality in Pressure Measurement Technology is unequalled in the industry. Behind every Model 831 low power transmitter is over 15 years of piezoresistive sensor chip and stainless steel diaphragm/oil isolation technology. Over these years, REQUIRES LESS THAN 30 MILLIWATTS TO OPERATE! AMETEK has developed and perfected test methods and quality checks to ensure that every transmitter will operate within specification in tough environments for years of service. The most advanced Automated Test Systems in the industry are used to characterize and final test every transmitter. In addition, every transmitter goes through numerous quality checks which verify secure assembly methods all the way through the production process. Nothing less than a 100% quality level is accepted. With this PMT quality commitment and our zero-defect philosophy, the AMETEK warranty is backed with confidence.
