Intelligent Transmitter Range

We supply radio transmitters with single and dual inputs. The intelligent sensors connect into the base of the transmitter via a miniature IP68 rated connector. The radio transmitters are battery powered and can supply power to the transmitter and sensor for 5+ years. Batteries are user replaceable through a screw lid. Each transmitter contains a high intensity LED and test switch providing local indication of connection to the network.

For larger installations, we can supply a range extender that increases the area covered. Multiple range extenders can be added to form a mesh style network allowing the transmitters to communicate over long distances and complex structures.

Range extenders are mains powered. Optional battery backup units are available.

Digital Rf transmitters for use with intelligent sensors

dual and single wireless transmitters

Digital Rf transmitters for use with intelligent sensors

Designed to work with Tek Troniks D3 wireless base stations and are compatible with a full range of Tek Troniks Intelligent sensors (see below). Long range secure communication protocols using licence free radio frequencies. Bi-directional wireless communications with the base station allows for communication status reporting. Can be used in environments where wash down is required. The screw top battery compartment allows for users to easily replace the battery, every 5 years. Dual input transmitters allows for 2 intelligent sensors to be connected on 2 separate channels.

Digital Rf range extender (Repeater Module)

wireless signal repeater transmitter

Digital Rf range extender (Repeater Module)

When covering large areas or where obstructions block the wireless transmitters natural signal path “Repeater” modules can be used. Using repeater modules forms an interconnected mesh of  repeaters which forward information from wireless transmitters, using the most efficient path, back to the base station. Should any individual repeater become inaccessible, alternate repeaters can be discovered by the transmitters and used, thus providing a robust and reliable network topography.

Intelligent Sensor Range

Our range of high accuracy sensors perform the necessary conversion from the measured factor to digital data which is then sent via an attached radio transmitter. Each intelligent sensor has its own unique id and can be updated with multi-point calibration data including the date it was last calibrated.

Intelligent temperature and humidity sensors can be provided with UKAS calibration. Intelligent sensors attach directly to single or dual input transmitters. If you can't see a sensor solution contact us for more details on our bespoke manufacturing offering.
