A Low Cost Universal Input Panel Meter for Temperature and Process Measurement.
You can find out more about the applications for the Tracker 211, for example as a digital temperature gauge, by visiting our applications section. Download related documentation from the area to the left or contact us to discuss your requirements further.
The Tracker 211 digital panel meter for low cost "no frills" applications, but in demanding industrial environments.
You can use the panel mounted Tracker 211 meter for measurement and display only applications or as an alarm trip
and with the analogue output option, it can also act as a transmitter.
An alarm relay is fitted as standard with a further 2 available as options.
You can directly connect the Tracker 211 to most popular process sensors including Thermocouples, RTDs, 20mA loop Transmitters and DC signals up to 100mV and 10V. The Tracker 211 digital panel meter will display temperature in °C or °F to 0.1 degree resolution. Millivolt, 10 volt and 20mA signals can be scaled to engineering units using any portion of the -1999 to 9999 display range (with an adjustable decimal point position). There are linearised thermocouple ranges for types K, T, J, N, R and S. Thermocouple inputs have automatic cold junction compensation (CJC) withup-scale sensor burnout detection. Two RTD (Pt100) ranges are also available. Zero, tare and max/min memory functions are available on versions fitted with front panel buttons.
Transducer / Transmitter Excitation Supplies
The Tracker 211 digital panel meter includes an isolated 24V DC transmitter supply as standard to provide power for 2-wire (4-20mA) sensors and a regulated 10V DC output for strain gauge type sensors such as pressure transducers and load cells.
Analogue Output (Option)
The Tracker 211 digital panel meter can transmit a measured value as a linear 4-20mA signal to other devices such as a chart recorder or data logger. The output can be scaled to any portion of the display range, e.g. 4-20mA = 500-800 (psi). The electrically isolated analogue output always follows the displayed value, so when using Thermocouples and RTDs, the output is linear to temperature, not the input. Reverse output is also configurable i.e. 0-100 = 20-4mA.
The Tracker 211 digital panel meter has one alarm relay fitted as standard and can be fitted with up to 3 alarm relays. You can configure Setpoints at the time of configuration or adjust them using buttons that are hidden behind the front panel. If you want to adjust the setpoints frequently then specify front panel buttons to be fitted. You can configure each alarm to be high or low acting and the relay energised or de-energised in the alarm condition and on/off hysteresis to stop relay chatter.
There are no internal pots, links or switches. The Tracker 211 can be configured using concealed buttons situated behind the front panel or front panel buttons if fitted. The instrument prompts the user for each setup parameter. For users who need to configure many units, a Windows compatible configuration program is available for setup, storage and downloading to the Tracker 211. A special adapter lead is available to connect an RS232 interface on the computer to the programming socket on the Tracker 211.
Front Panel Buttons (Option)
As an option, front panel buttons can be fitted to allow fast and easy access to the alarm setpoints or when the tare, zero or max/min functions are to be used.
Units of Measurement
Engineering unit labels for the most common measurements including temperature, flow, distance, power and pressure are supplied with each instrument.
Universal Power Input
Wide ranging 90-265V AC power input allows world-wide installation. A 24V AC/DC version is also available.

A low cost 5-Digit, universal process and temperature indicator with linearisation features for 4-20mA tank contents signals.
The Tracker 212 is a budget panel meter that supports the features and performance usually found in more expensive products. Being quick and easy to configure, with a 5 digit display and 24 point user linearization, the Tracker 212 is well suited to tank contents, process and temperature measurement applications. You can contact us without obligation to discuss your particular requirements further if you wish.
Tank Contents and Process Measurement
Up to 24 user linearisation calibration points can be entered corresponding to a 4-20mA signal, ideal for tank contents applications. A regulated 10VDC excitation supply is provided for "bridge" type sensors and a 24VDC supply for two wire transmitters and active sensors. The Tracker 212 can also accept mV and 10 volt signals.
The Tracker 212 can be wired directly to thermocouples, RTD's or temperature transmitters. Select the thermosensor type from the menu and the input is automatically scaled and linearised and is user selectable for display in °C or °F with a resolution of 1° or 0.1°.
The Tracker 212 is fitted with a relay output with volt free C/O contacts, as standard. The alarm can be high or low acting with user selectable alarm hysteresis. The relay configurable to be energised or de-energised (fail safe) when in the alarm condition. Two further alarm relays can be fitted as an option.
The analogue output option gives an isolated 4-20mA signal, which is scalable to any portion of the display range. The output is linear to the displayed value, not the input. This makes the Tracker 212 an ideal tank contents or temperature transmitter.
You can fix alarm setpoints at the time of configuration or adjust them using buttons hidden behind the front panel. If you need to adjust the setpoints frequently then front panel buttons can be fitted.
The Tracker 212 can be setup using the concealed configuration buttons, which are situated behind the front panel, or using the front panel buttons if fitted. The T212 prompts the user for each set-up parameter. For users that need to configure a number of units, a PC compatible configuration program is available for setup, storage and downloading of configurations to the T212. A special adapter lead is available to connect an RS232 interface on a computer to the programming jack socket on the rear panel of the Tracker 212.
