The TR200 indicator is a completely portable, 4½ digit precision instrument that is ideally suited for use in the harshest of environments or in the laboratory. It is designed to accept the signal from any strain gauge based sensor, with an output sensitivity of up to ±60mV/V.
The menu structure facilitates Auto Calibration, Decimal Point Position setting, Fixed Zero (count-by) setting and Digital Filtering rate. Auto-Zero and Peak/Valley Hold functions are available on the front panel, with single key press operation.
The menu options offer the engineer the ability to tailor the instrument to an application. Once set, all the menu keys can be disabled to provide the user with the simplest of indicators ideally matched to their requirements. The TR200 is able to store the parameters for up to 10 sensors, making it ideal for multi-sensor monitoring; allowing switching from one sensor to another, without the need of any calibration adjustment.
System expansions are available to enhance the TR200 capabilities. These include; RS232 output for printing or data log downloading, Intelligent sensor recognition, allowing automatic recall of a sensors parameters when it is plugged in to the TR200. Additional options include; Dual Trip outputs, Voltage and Current outputs and Data Logging.
The TR200 is supplied complete with a universal 110/230vac battery charger and carry case.

The TR200 can be supplied calibrated as a system with any of LCM Systems products. If ordered with any sensor, this calibration will be performed, with traceability to UK National Standards at no extra cost.
|The options detailed below are standard options, which are readily available. They are internally fitted to the TR200. The options can either be fitted singularly or combined to expand the TR200 further. LCM Systems have produced a large number of variants of the TR200 and welcome enquiries for the more unusual or specialist applications.
