All About Class I Division 1 Electronic Mass Flow and Pressure Instruments
IS-Max™ & IS-Pro™ bring digital metering and control for CID1 settings, without explosion proof housings!
Proportional control with increased automation
- Up to 13 reported parameters on flow, pressure, temperature, etc.
- Relative humidity reporting option, ideal for humid hydrogen processes
- Accurate, repeatable digital measurement, measuring 1,000 times per second
- Use digital comms, set point, alarms, and totalizer in your system automation and reduce manual intervention in hazlocs
- IP66 ingress protection appropriate for analyzer shelters, environmental monitoring, or shaded outdoor areas
Alicat’s family of intrinsically safe instruments
IS‑Max mass flow meters and controllers
IS-Max intrinsically safe flow meters and MFCs for natural gas, hydrogen & more rated for class I division 1, IECEx, and ATEX Zone 0.
IS‑Pro pressure gauges and controllers
IS-Pro intrinsically safe pressure controllers and meters, great for back pressure control or dome-loaded pressure regulators in class I division 1, IECEx, and ATEX Zone 0 settings.
IS‑Pro pressure gauges and controllers
IS-Pro intrinsically safe pressure controllers and meters, great for back pressure control or dome-loaded pressure regulators in class I division 1, IECEx, and ATEX Zone 0 settings.
Why switch to an electronic flow and pressure controller in class I division 1, or division 2 zones?
- Protection from drifting measurements
- More insight into the process through a greater range of sensors and data
- Higher precision, more adaptable pressure and/or flow control
- Fewer components in the system
- Validated analysis results
What is ‘intrinsically safe’?
Intrinsically safe is a protection concept for hazardous zones. In short, an intrinsically safe device is one that does not produce enough heat or power current to cause combustion when surrounded by flammable gas or vapor.
Whether you are working in an area where hazardous gases are continuously present (class I div 1), or only during abnormal circumstances (class I div 2), it’s recommended, if not explicitly required, to use equipment that is intrinsically safe.
Supported applications
By working closely with our customers, Alicat has fostered a collaborative environment to help build custom solutions for critical processes, here are a few of the industries.
Gas chromatography & analysis labs
Benefits of IS‑Max and IS‑Pro for chemical analysis
- Data logging for easier troubleshooting and diagnostics
- No manual adjustment due to operating conditions
- Digital communication allowing devices to be read (or controlled) from outside the hazardous zone
Hydrogen electrolysis and fuel cell test stands
Benefits of IS‑Max and IS‑Pro for hydrogen
- Dew point sensing to control condensation
- Scripting power to quickly change test parameters
- Flow visualization and data-logging tools easily integrate with lab software
Chemical analysis and environmental monitoring for oil & gas
Benefits of IS‑Max and IS‑Pro for analyzers & environmental
- IP66 ingress protection appropriate for analyzer shelters, environmental monitoring, or shaded outdoor areas
- Valve usage data for improved preventive maintenance cycling
- Scripting and remote control/data collection capabilities
