SMART SENSING FROM SONTAY

28th October 2019

Sontay, the market leading manufacturer of field control devices, is delighted to launch a new generation of intuitive Smart Sensors. This new range incorporates all the great functionality of the first-generation sensors but with added features that meet the needs of the installer and the end user. 
 
“Back in 2015 we were one of the first to introduce a “Smart Sensing” device that could communicate via BACnet or Modbus protocols,” says Sandy Damm, Managing Director at Sontay. “The Smart Sensor received praise and acclaim from many of our customers and it is currently installed in smart building projects across the world. Now, we have gone a stage further and are launching a range that will revolutionise smart sensing.”

The original sensors had the ability to combine up to nine different measurement variables and a user interface option within a device. This was a significant step when they were first launched as it offered a major advantage in reducing cabling to the controller as well as the utilisation of the controller IO. 
 
Sontay is now introducing the next generation of Smart Sensors that can offer full environmental sensing in one single device. These sensors can measure temperature, relative humidity, carbon dioxide, indoor air quality (VOC), carbon monoxide and light level as well as offering PIR detection.

The sensors are inherently smart and utilise smart protocols. The RS-485 data bus interface supports the communication protocols BACnet MS/TP and Modbus RTU. The DIP switch allows for configuration of network parameters and lets users select BACnet MS/TP or Modbus. All other configurations that are required can be made via the BACnet or Modbus network meaning that no separate equipment or configuration tools are needed. 

The BACnet compatible devices will find the baud rate of the network and adjust the device baud rate automatically after start-up saving time. They also offer auto device instance configuration, which provides out-of-the box functionality for smaller projects.

Additional new features include two digital and three analogue outputs. The former can be configured as a volt free contact whilst the latter can be configured as an additional thermistor (10K3A1) input or a 0-10Vdc input. The Digital outputs are intended to switch plants on/off and can be configured to be driven by the network or the option momentary switch option. The analogue outputs can be configured to map sensor variables or any network value.

Sandy continues, “Our customers have been asking us about a smart sensor that can offer these features and capabilities for a while. We have listened and have dedicated a vast amount of time and development in manufacturing a product that meets their requirements - it is the most advanced solution available on the market. We are sure our customers are going to be impressed with the quality, functionality and reliability of the new Smart Sensors.”

Sontay produces the most comprehensive control peripherals offering to the UK building services market. All Sontay products are renowned for their accuracy, reliability and discrete appearance and are used by many of the market leaders in the worldwide building controls industry. Their products and control solutions help improve building management system performance, reduce energy and maintenance costs and increase occupant comfort levels.
