Description:

Industrial Temperature measurements are usually using Thermocouples, RTD or other Resistance sensors. Some applications a 2-wire transmitter may be used, particularly if distances between the sensor and the instrumentation are large.

The following instruments can measure thermocouples and RTD directly or power and measure 2-wire transmitters:

• Tracker 210 Low Cost 4-Digit Indicator

• Tracker 212 Low Cost 5-Digit with 4-20mA signal linearisation

• Tracker 220 Series - High accuracy 4/5-Digit + RS485

• Tracker 250 5-Digit Melt Pressure - Auto Calibration resistor switching + RS485

• Tracker 300 series DIN Rail modules + RS485 (+PID on some models)

All the products listed above have the following as standard or can be lifted as an option:

• Isolated analogue output

• Alarm relays

• Max/min memory + reset

• User calibration function:

• Using the user calibration feature, the Tracker and sensor can be match calibrated together where the instrument measures and stores the sensors signal at two known temperatures. This greatly reduces errors due to sensor output variations. The displayed values can be in °C or °F (and Kelvin on the 220 and 300 series).

All Tracker temperature measuring instruments have an automatic Cold Junction Compensation (CJC). On the Tracker 220 series the user can also select an external reference junction temperature and select up- or down-scale sensor break detection.

In applications where non-linearising temperature transmitters are used, the Tracker 220 series can linearise a 4-20 mA signal to the required thermocouple curve.

Description:

Pressure and weighing sensors are generally supplied as a 350? strain gauge bridge device, requiring a regulated excitation supply and outputting a millivolt signal, or a 2-wire transmitter which requires a 24VDC supply and outputs a 4-20mA signal.

The following instruments can power and measure both these sensor types:

• Tracker 210 Low Cost 4-Digit Indicator

• Tracker 212 Low Cost 5-Digit with 4-20mA signal linearisation

• Tracker 220 Series - High accuracy 4/5-Digit + RS485

• Tracker 250 5-Digit Melt Pressure - Auto Calibration resistor switching + RS485

• Tracker 321 and 332 (PID) DIN Rail modules + RS485

• For multiple load cells (multiple strain gauge bridges):

• Tracker 240 5-Digit Load Cell Indicator + RS485

All the products listed above have the following as standard or can be lifted as an option:

• Isolated analogue output

• Alarm relays

• Zero function

• Tare function

• Max/min memory + reset

• User calibration function:

• Using the user calibration feature, the Tracker and sensor can be match calibrated together where the instrument measures and stores the sensors signal at two or more pressures or weights. This greatly reduces errors due to sensor output and excitation supply voltage variations. The displayed values can be in any engineering units.

On the 200 series a front panel button, or status (logic) inputs on some models, can be configured to provide an auto zero feature allowing zero offset errors to be eliminated. For weighing applications, a tare function can be similarly configured.

For zero and tare functions on a T300 command must be sent via the RS485 interface or remote switches connected to the status inputs on the T340 logic expansion module.

Description:

Industrial signals are loosely associated as process are 0-5VDC, 0-10VDC, millivolts DC and the most popular 20mA loops (e.g. 4-20mA). These are scaled as a range in engineering units e.g. 0-10VDC = 0-500 Litres Per Hour.

The Tracker Instruments that can accept ±20mA, ±10VDC and ±100mV are:

• Tracker 211 4-Digit Low Cost

• Tracker 212 5-Digit Low Cost with 4-20mA Linearisation

• Tracker 220 Series 4/5-Digit High Accuracy + RS485

• Tracker 250 5-Digit Melt Pressure Indicator + RS485

• Tracker 300 DIN rail mounted + RS485

All of the above have as standard or can be fitted as an option:

• 10V and 24VDC sensor/loop excitation supplies (standard all models)

• Isolated analogue output

• Alarm relays

• Zero function

• Tare function

• Max/min and reset

All the instruments listed above can also connect directly to thermocouples and RTD temperature sensors making their inputs "Universal".

Description:

Analogue outputs are used to isolate and transmit a value in form of a analogue signal. For example to transmit a temperature measured by a Type K Thermocouple as 4-20mA = 0-500°C.

The following Instruments have analogue outputs or options:

• Tracker 211 4-Digit Low Cost - Optional 4-20mA output

• Tracker 212 5-Digit Low Cost - Optional 4-20mA output

• Tracker 223 & 224 5-Digit High accuracy - 0/4-20mA / 0-10VDC (Fitted as standard)

• Tracker 240 5-Digit Load Cell Indicator - 0/4-20mA / 0-10VDC (Fitted as standard)

• Tracker 250 5-Digit Melt Pressure Indicator - 0/4-20mA / 0-10VDC (Fitted as standard)

• Tracker 260 5-Digit LVDT Indicator - 0/4-20mA / 0-10VDC (Fitted as standard)

• Tracker 280 5-Digit Counter/Timer Indicator - 0/4-20mA / 0-10VDC (Fitted as standard)

• Tracker 300 series DIN rail Instruments - Optional 0/4-20mA / 0-10VDC

The output can be configured to transmit the measured value or the averaged, maximum or minimum value. It has its own damping filter for noisy or fast moving signals. The input can be locally conditioned and re-transmitted over a long distance. Being electrically isolated, problems associated with earth loops causing noisy and inaccurate measurements are eliminated.

If 4-20mA outputs are configured then the analogue output signal will not fall below 4mA or exceed 20mA.
