Product Data ELECTRONIC PRESSURE MEASUREMENT PRODUCTS Model 831 Pressure Transmitter DESCRIPTION The Model 831 transmitters are the most durable, accurate and cost-effective fixed range pressure transmitter available. An all 316 stainless steel transmitter, it is designed for years of stable performance in even the toughest environmental and corrosive media conditions. With its all-welded construction, this transmitter is weatherproof and capable of a direct spray with forces up to 200 psi without internal leakage. The Model 831 (standard and low power) has FM and CSA explosionproof ratings. The 831D (differential pressure) also carries the CSA explosion-proof rating. All Model 831s meet NACE standards for offshore applications. A one year warranty is standard with every unit. l Available in differential pressure, low power or stan- The small size and light weight of the Model 831 transmitter eliminates the need for complicated mounting hardware and mechanical supports, thereby substantially reducing installation time. The in-line connection permits simple field wiring without the need for additional hardware, adding to the speed and ease of installation. The standard Model 831 and the Model 831D feature a 4 to 20 mA output standard with a 12 to 30 VDC power supply. The Model 831 Low Power 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 applications on battery or solar power. This model requires 6 or 8-14 VDC excitation and is available in pressure ranges from 6 to 5000 psi. dard version l All welded 316L stainless steel construction and wet- ted parts l 3/4 inch NPT female conduit connection cable l 1/2 inch NPT female pressure port, 1/2 inch NPT male, 1/4 inch NPT male l 24 inch cable length standard l All models are CSA approved, explosion proof, and meet NACE standards for off-shore applications l The low power and standard versions are FM ap- proved with the explosion proof rating PRODUCT FEATURES Model 831 Standard l Available in pressure ranges from 6 psig to 5000 psig l Rugged construction l Available with conduit adapter l Optional EMI protection Model 831 Low Power l Available in pressure ranges from 6 psig to 5000 psig l 8 to 14 or 6 to 14 VDC with reverse polarity protection l Perfect for solar or battery applications l Current draw <3 mA l Optional EMI protection Model 831D l Measures differential pressure l Available in pressure ranges from 6 psid to 500 psid Models 831, 831 Low Power and 831D Differential Pressure Transmitters with various output options Sales/Technical Support Telephone: +1 215-355-6900 or e-mail: pmt.sales@ametek.com 820 Pennsylvania Boulevard | Feasterville, PA 19053 U.S.A. | Order Fax: +1 215-354-1802 © 2013, by AMETEK, Inc.
