Sieger Signalpoint Pro

The Signalpoint Pro is an intrinsically safe, cost effective, toxic and Oxygen gas detector for use in the toughest environmental conditions. A 2-wire, 4-20mA loop powered device that can be used indoors or outdoors in areas that are routinely washed or hosed down.

Signalpoint Pro is designed for user friendly operation along with simplified installation and maintenance. A removable cover allows sensors to simply plug into the transmitter without having to open the main terminal housing. The gas type and default sensor range for each sensor is automatically recognised and displayed on the built-in display.

Hidden push buttons provide user programmable features such as gas range and calibration gas level setting. Non intrusive, one-man calibration is initiated by a magnetically operated switch. The Quick Calibration routine, including auto-inhibit to prevent false alarms, walks the user through the process using a series of on-screen prompts to ensure right first time set-up and operation.

The large terminal compartment includes a hinged cover to provide easy hands free access for wiring. When opened, fixing points are revealed providing secure hidden mounting. A pre-formed M20 clearance cable entry is provided with a second easy knockout entry if required.

Signalpoint Pro is ideal for use with a range of dedicated gas monitoring controllers or industry standard PLCs. Either way, users are assured of being protected in all conditions by Sieger gas monitoring solutions.
