KJ91

KJ92

＊25.4mm conversion fitting supplied as option.

Features of sensor

Compact size and light-weight with the same appearance and operability as non-intrinsically safe GC51 and GC52.Adjustable indication and output scaling are available. Breakthrough readability with LED-backlit LCDBecause the insulated safety barrier is used, Type A intrinsic safety ground work is unnecessary.

They are two types of 2-wire intrinsically safe pressure and differential transmitter, the GC51 based product utilizing SS sensor and GC52 based product utilizing SC sensor. Make sure to use with insulated safety barrier. It can be used in (ZONE 0) place where potentially explosive gas always exists. It conforms to IEC based intrinsically safe specification. (Explosion class: Exia ⅡC T4)In combination with non-intrinsically safe GC51/GC52, it can be used in a wide range of industrial process measurements (Low pressure to high pressure).

Semiconductor Evaporated type (SS) Sensor

The semiconductor evaporated type (SS) sensor, which ability has been proven in various industrial fields, has an integral construction from the semiconductor strain gauge part and sensing part to pressure connection part, and no adhesives or corrosive materials are used. It helps for superior durability and stability.

Silicon Capacitance (SC) Sensor

Since the sensor section contains a sealed-in silicon capacitance (SC) sensor formed by micromachining and the wetted parts consist of a stainless steel diaphragm, it handles a wide range of medium and can measure fine differential pressure with high reliability and high sensitivity.

Function

Panel display

①LCD display　The bright and clear LED backlight ensures excellent visibility in a dark place and night time.②Scaling　Pressure linearly converted to an arbitrary physical quantity and displayed/output.③Zero adjustment　The zero point at 4 to 20mA DC can be adjusted by key operation.④Loop check　Without applying pressure, 4 to 20 mA DC can be output arbitrarily. This makes maintenance easy.⑤Filter　Pulsations and other pressure changes can be smoothened by moving averages to reduce display fluctuations.⑥Holding display　Both the maximum value (Peak) and the minimum value (Bottom) can be indicated.

①LCD display　The bright and clear LED backlight ensures excellent visibility in a dark place and night time.②Scaling　Differential pressure linearly converted to an arbitrary physical quantity and displayed/output.　The square root of the differential pressure is extracted and the instantaneous flow is displayed and output.③Zero adjustment　The zero point at 4 to 20mA DC can be adjusted by key operation.④Loop check　Without applying pressure, 4 to 20 mA DC can be output arbitrarily. This makes maintenance easy.⑤Filter　Pulsations and other differential pressure changes can be smoothened by moving averages to reduce display fluctuations.⑥Integrated volume display　The integrated volume is displayed form independently from or alternately with the scaling.
