JETI MT-125 Temperature Sensor

The JETI MT 125 EX Sensor is used to measure temperature of devices like motors, controllers, batteries, and other model accessories. The measured data can be displayed by a JETIBOX terminal and the wireless telemetry information transfer with the aid of the JETI DUPLEX 2.4GHz radio system.

The Duplex System takes advantage of the 2,4GHz-Band for communication which allows not only the transfer of remote control data to the model, but also in the opposite direction to the transmitter. The telemetry data measured during operation is transmitted in real time and the actual state of the data can be displayed on the JETIBOX LCD-display. The MT unit records minimum and maximum temperatures of the individual sensors and their actual values.

The JETIBOX terminal takes care of parameter adjustments as well as indication of measured data.
The MT 125 EX device consists of two parts. The MT 125 EX module itself, which records the data measured by the temperature sensors connected to the MT 125 EX module which can be connected to the JETIBOX or to a receiver or an Expander of the DUPLEX system. Keep an eye on the temperatures of the module and sensors in order not to expose them to temperatures higher than allowable.

The MT 125 EX module allows triggering of audio alerts by the individual sensors. These alerts can report temperature limit violations i.e. too high or too low with temperatures exceeding the set limits. The audio signal is generated by the transmitter module DUPLEX Tx which contains a small siren. The signals are differentiated by Morse codes in order to be able to distinguish between the individual types of alerts referring to individual sensors. The audio signalling of parameter violations will be generated even if there is no JETIBOX available. With a JETIBOX connected there will be an indication on its display showing which parameter is in alarm. If several parameters are in alarm at the same time, the alert sounds change consecutively as well as the indications on the JETIBOX LCD-display.
