Electrical Review

A new wireless temperature monitoring solution from field controls and peripherals expert, Sontay, will bring better legionella control alongside significant savings in maintenance time, cost and fuel bills for building owners and facilities managers.

Developed by Sontay in partnership with legionella specialist, H2O Chemicals, the SonNet family of wireless sensing devices features battery powered sensor nodes together with permanently powered network receivers and routers, and software. SonNet sensors are designed around a robust 2.4 GHz, 802.15.4 self-healing tree topology to provide consistent measurement of water and air cooling system temperature at set frequencies and periods in the day. These readings are then communicated to the building’s control system, helping to identify any trends or out of specification temperatures and so control the risk from legionella.

Using SonNet wireless sensor technology also significantly reduces the amount of manpower required to implement a full legionella monitoring programme.

E-Matic has further enhanced its occupancy sensor range. The new PMSM retrofit microwave sensor is suitable for integrating into a variety of fixtures with diffusers constructed of glass, acrylic or PVC.

As the sensor fits neatly into a fitting, instant energy & cost savings are achieved with no additional cabling required or need for replacing fittings. 

As the sensor uses high frequency microwave technology, the sensor can be hidden from view, great for installations where the aesthetics are important.

With the PMSM, your existing fitting becomes the occupancy sensor.

Suitable for many types of load including incandescent, fluorescent, PL and LED, the retrofit occupancy sensor is an ideal energy saving solution for many existing lighting installations.
