Certifications
Our ATEX/IECEx Intrinsically Safe IS-Max and IS-Pro devices are approved for use in potentially explosive environments:
Included with each device
- Valve close override and valve open override: Utilize alarms to quickly vent your system or stop all flow as needed.
- Monochrome backlit LCD with integrated touchpad: Easily read measurements using the backlit display and control configurations with the user-friendly integrated touchpad.
- User-adjustable setpoint ramping & limits: Configurable ramp rates allow the process variable to be controlled as fast or as slow as desired, and configurable setpoint limits protect processes from inadvertent setpoint changes.
- User-adjustable standard temperature and pressure (STP) conditions: Quickly change reference conditions without the need for recalibration.
Accessories | Sold separately
- Process port fittings and filters
- Required barriers for power supply and communication
