Flameproof Instruments

Ashe offers a wide range of process measurement and control instruments in Flame-proof / Explosion-proof execution for operation in hazardous area applications. The instruments are designed for use in industries where high degree of vibration, inclement weather and corrosive atmospheres prevail.

The electronics is mounted inside low-copper, epoxy coated die-cast Aluminum enclosures, which have a Safety Glass window for process and control indication. For more aggressive environments, Stainless Steel SS-316 versions are also offered. Instruments such as Digital Loop Powered Indicators, Digital process Indicators for all applications, On/Off Controllers, Flow Totalizers and Batch Controllers, Temperature Transmitters, Earthing Relays, etc., are offered in this execution.

The enclosures are compact, rugged and aesthetically designed. They are offered in attractive colors for Aluminum enclosures and Natural Silver color for Stainless Steel SS-316 enclosures. Complete mounting accessories are offered for field or 2” pipe mounting. The enclosures are certified for use in Gas Groups IIA and IIB and Zone 1 and 2 atmosphere by CIMFR, Dhanbad for Flame-proof applications as per IS:2148-1981 and Weather-proof applications for IP-65 protection as per IS:13947(Part-1):1993.

All ASHE instruments carry a lifetime warranty against defects in components and workmanship.

The ASHE Model JB-40 Digital Battery Powered Temperature Indicator is a compact, rugged and reliable indicating instrument which is self-contained and specifically designed for accurate temperature measurement applications, in areas without power availability.

The instrument is micro-controller based and operates on battery power, having provision for two AA battery cells in parallel configuration. The Indicator accepts either a standard J or K type Thermocouple sensor at its input terminals and displays the actual temperature value calibrated in the desired units, on a linear scale.

The process value is displayed on a 3-1/2 Digit seven-segment LCD digital display module. The instrument can be calibrated on any scale range from -1999 to +1999 units. The two thermocouple inputs are factory calibrated for a range of 0-750°C (1382°F) for J type thermocouple and 0-1000 °C (1832 °F) for K type thermocouple.

The Temperature Indicator is specifically designed to operate on minimal power consumption and provided temperature readings for extensive period on battery power alone. While the microcontroller is continuously sampling the input signal, it refreshes the display at ten-second intervals with the updated internal readings. A Power-On switch is provided to switch off the instrument when not in use, thereby saving battery life.

Further, the temperature reading is available in both, Celsius and Fahrenheit units. A switch is provided for selecting the desired unit. The JB-40 Indicator is therefore an ideal signal unit substitute to conventional analog indicators because of its inherent accuracy in process measurement, besides other superior characteristics such as extremely low power consumption, immunity to Shocks, Dust, Ambient temperatures, Humidity and Corrosive atmospheres. Its main advantage is that it operates on minimal power, providing several months of uninterrupted indication of the measured temperature.

Further, the instrument is manufactured using selected highgrade components which guarantee its reliability and long operational life. The unit also has no moving parts, which greatly enhances its versatility.
