Explosion-proof instruments>> Indicating & Control 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.

The ASHE range of Process Indicators and Controllers are compact, rugged and reliable indicating instruments designed for accurate measurement and control applications.

The range covers a wide spectrum of products offering indication and control in various formats, some of which are :

Digital Indication – LCD and LED in various dimensions & executions
Numeric and Alphanumeric Indicators
Loop Powered Indicators
Bar-Graph Indicators
Battery powered Indicators
Multiple Relay control outputs
Various Control actions – like On-Off, PID, Time delay, etc.

The Indicators accept all industrial standard input signals, like 4 to 20 mA DC, AC/DC Voltage, AC/DC Current, Resistance, Strain-gauge, Frequency and all temperature sensors like RTD Pt-100, Thermocouples, etc. The process value is displayed on a 3-1/2, 4 or 4-1/2 digit seven-segment LED or LCD digital display. Up to four relay outputs are available as control options, each of which can switch a load of up to 10 Ampere rating.

These micro-controller based Digital Indicators and Controllers are also offered in several dimensions in panel mounted execution and operate on AC or DC power supply, as required.

Options include analog retransmission signals, DIN rail mount / weather-proof / flame-proof executions, Remote Control operation, etc.

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