Tracker 300 predicts thermocouple
replacement
The new Tracker 300 range, recently launched by Data Track, has a standard feature that constantly monitors the condition of a thermocouple and warns the user if the sensor needs replacement
Sudden and unexpected thermocouple failure can be expensive if it results in lost production and unscheduled downtime The new Tracker 300 range, recently launched by Data Track Process Instruments has a standard feature that constantly monitors the condition of a thermocouple and warns the user if the sensor needs replacement, so a user is aware of the problem before a failure occurs, allowing planned replacement, saving maintenance costs, and increasing production revenue

Complete the Data Track survey and win a camera
The new Data Track website is a real win/win story for process engineers: easy to use and full of useful data, there is a survey that takes less than 2 minutes to complete, with a camera as a prize!
The DIN rail mounted Tracker 300 employs a new method to determine the potential failure of thermocouples.
It works by measuring the loop resistance of a new thermocouple when it is initially connected, then storing this value in memory.
By periodically monitoring the loop resistance and comparing it to the stored value, the ageing effect and condition of the thermocouple can be determined.
Users can choose from PID, alarm trip, signal conditioning and isolator options for the Tracker 300.
All the units are supplied with a universal input covering mA, mV, V, thermocouple, PT100, resistance and strain gauge measurements and each has RS485 Modbus communications fitted as standard.
Other standard features include square root functions, user linearisation, sensor and transmitter power supplies.
The unit can be programmed remotely via the RS485 link or locally using a front panel connector; in each case, PC based configuration software is available.
Front panel LEDs give status readings on communications and alarm conditions.
The Tracker 300 can be supplied with relay, SSR and analogue outputs.
The Tracker 340 logic module provides extra expansion, giving a combination of up to four additional relays or TTL outputs and two logic inputs.
The Tracker 300 provides true single loop integrity in a compact 22.5mm wide housing.
