Model JH

Using high pressure autoclave fittings, the Series JH digital pressure test gauge with 0.2 % full scale accuracy uses transducer technology and is manufactured from 15-5 PH Stainess Steel wetted material for high over pressure protection. The transducer technology provides enhanced accuracy over the entire pressure range.

The JH 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 JH 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. PSI pressures are read x 10 with the 4½-digit display.

The Model JHB provides a 4 mA to 20 mA, two-wire output. The Model JHE provides a 0 Vdc to 5 Vdc output. The Model JHR has two programmable limits and relays with no analog output. The Model JHX provides a 0 Vdc to 5 Vdc output with two programmable limits and relays for process control or alarm indication. The Model JHW is powered by one or two common 9 V alkaline batteries. The Model JHT is powered by a 110 Vac adapter. The JHV, JHB, JHE, JHR and JHX models are 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 deactivated.
