Detecting SF6 leaks in switchgear
with InfraSensing's ENV-GAS-SF6 sensor
SF6 (sulfur hexafluoride) is a synthetic, man-made gas that is used in switchgear because it has a high dielectric strength and a low arc-quenching time. This means that it can effectively insulate and protect electrical equipment from damage due to high voltage arcing.
NDIR (non-dispersive infrared) SF6 gas sensors from InfraSensing are the best technology for detecting SF6 leaks because they are highly sensitive and accurate. They work by measuring the absorption of infrared light by the SF6 gas, which allows them to detect even very small leaks.
If an SF6 leak goes undetected, there are several risks. First, the gas is a potent greenhouse gas that contributes to global warming. Second, SF6 is a toxic gas that can be harmful to human health if inhaled in large amounts. Finally, if an SF6 leak goes undetected, it can cause damage to electrical equipment, which can lead to costly repairs or even system failures.

calibration & bump testing
Prior to shipping every gas sensor is manually tested in our lab against calibrated gas.
For bump testing we offer the optional SPARE-GAS-BUMP adapter which is mounted on to the sensor. It enables you to self test the sensor at intervals to ensure its operation within your own safety & operational requirements. Do note that each bump test impacts the sensor life span and accuracy. Incorrect bump testing may permanently damage the sensor.

modular architecture
A modular architecture enabling you to integrate it with your on-premises monitoring systems using IP based industrial protocols like Modbus TCP and SNMP. Optional add-on to connect sensor data to a Modbus RTU controller. With our optional and special firmware the base unit can connect to a MQTT provider of your choice.
With the output controls of the SensorHub, the system can on its own take corrective actions when threshold levels have been detected. For example you can start a fan as soon as a specific is detected.

No PC or Software Required
The InfraSensing sensors connect to the base unit (BASE-WIRED). The base unit is a standalone device that has its own IP address in your network. On its own it will monitor the sensor and trigger alerts via email, SNMP or optional SMS when needed.
There is no software or PC required for the sensors to run.
With our optional Monitoring Software you can centrally monitor sensors with trending and more. This is optional and not required.
Wired or Wireless
By default all sensors are connected to the SensorGateway (BASE-WIRED) using a CAT6 or higher RJ45 cable.
Using the optional Wireless Hub & Node modules, any sensor can be turned into a wireless sensor.
