Model JS

The Model JS digital pressure test gauge with 0.2 % full scale accuracy uses transducer technology and is manufactured from Ha C276/316 Stainless Steel wetted material for ranges up to 1500 psi or 15-5 PH Stainless Steel wetted material for ranges 1500 psi and above for high over pressure protection.

The transducer technology provides enhanced accuracy over the entire pressure range. The JS 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 JS provides high resolution with an easy to read digital 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 in-hg, ft-water, etc.

The Model JSB provides a 4 mA to 20 mA, two-wire output. The Model JSE provides a 0 Vdc to 5 Vdc output. The Model JSR has two programmable limits and relays with no analog output. The Model JSX provides a 0 Vdc to 5 Vdc output with two programmable limits and relays for process control or alarm indication.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.
