Using Tri-Clover sanitary fittings, the Series JP digital pressure test gauge with 0.2% full scale accuracy uses transducer technology and manufactured from Ha C276/316 Stainless Steel wetted material for high over pressure protection. The transducer technology provides enhanced accuracy over the entire pressure range. The JP has no moving parts and thus, may provide a long life with fewer re-calibrations. The stainless steel NEMA construction also provides EMI and RFI protection.The JP provides high resolution with an easy to read 4½-digit display. There are no operator errors due to interpolation of hash marks or parallax errors. The units can be scaled to read in various engineering units such as InHg, Ft H2O, etc. The Model JPB provides a 4 mA to 20 mA, two-wire output. The Model JPE provides a 0 Vdc to 5 Vdc output. The Model JPR has two programmable limits and relays with no analog output. The Model JPX provides a 0 Vdc to 5 Vdc output with two programmable limits and relays for process control or alarm indication.The Model JPW is powered by one or two common 9 V alkaline batteries. The Model JPT is powered by a 110 Vac adapter. The Model JPV is powered by an 11 Vdc to 32 Vdc power supply. Each unit has a membrane face with raised buttons and tactile feedback for setup and operation. The high, low, and clear buttons are easily accessible on this front membrane. Zero adjustment and zero offset/tare functions are standard on each unit. Calibration and setup parameters are stored on a memory chip to protect from loss even when power is interrupted. Unauthorized set ups and calibrations are also blocked with internal security. Various combinations of the front panel buttons can be de-activated.
