Description
The new TEDS enabled portable strain gauge sensor display TRX by Applied Measurements is a microprocessor-based portable display for all types of strain gauge bridge sensors with an output sensitivity from 0.5mV/V right up to 480mV/V. It is a direct replacement for the TR150 handheld display, with additional channels and features.
The display can be used as a handheld device (like the TR150) and also comes with optional mounting accessories for desks, walls and magnetic equipment.
The basic version offers 2 calibration channels/ranges, allowing optimised calibration of bi-directional transducers to give the best possible accuracy in tension and compression (or clockwise and counter-clockwise in the case of torque transducers. Each channel also offers enhanced calibration options in the form of either a linearised calibration or a polynomial calibration to give even greater accuracy from your strain gauge-based transducer. Plus, it supports TEDS templates 33 (bridge sensors template), 40 (multiple data pairs), and 41 (calibration curve polynomial).
Once calibrated in your preferred engineering units, you can switch freely between various other engineering units according to your sensor type at the press of a button; i.e bar to psi (pressure), kg to Newtons (force), Nm to lb-ft (torque), and so on.
The free downloadable toolkit software enables advanced calibration and configuration options as well as data logging via the free Toolkit software, while simple configuration and 2-point calibration can be easily done/completed using the front panel buttons. The TRX is supplied with a micro USB cable to allow for Toolkit interaction and to enable the TRX operate indefinitely from a USB power source, if required.
Functions on the TRX include:
- Switching Between Engineering Units
- Range Selection
- Display Hold/Freeze
- Gross/Net indication selection
- Peak Hold selection
- Trough Hold selection
- TEDS support

TEDS Functionality
TEDS delivers a simple ‘plug and play’ technology. You simply connect a TEDS integrated sensor into the TRX and the information stored on the integrated TEDS chip transfers the critical calibration information to and from the connected TEDS devices.
TEDS equipment is interchangeable without having to recalibrate the devices. The TRX strain gauge display will remember the last 20 TEDS devices that have been connected to it.
The TEDS information that can be read by the TRX consists of the TEDS bridge sensors transducer template 33 which includes the sensor manufacturer, model, and serial numbers, the calibration template table 40 (maximum calibration points of 10) and the calibration curve template 41 (up to a maximum number of segments of 1 and a maximum number of coefficients = 10).
The TRX strain gauge display also gives the user the option to ignore the TEDS data and use the TRX calibration ranges instead.
The Display
128 x 64 monochrome dot matrix display with backlight. The display will change depending on the mode and options you have enabled. Below are some examples of a 3 value display and a simple display.

TRX Accessories
If you need to mount the TRX Strain Gauge Sensor Display to non-ferromagnetic surface then the Fixed Mount is the accessory for you. The mount is comprised of three parts which clip together to form two ball joints allowing the TRX to be angled in any direction you like. The base of the mount has numerous screw holes to allow easy installation.
If you are able to mount the TRX Strain Gauge Sensor Display to a supportive ferromagnetic surface then the Magnetic Mount is the accessory for you. The mount comes as one part that includes one internal ball joint to allow the TRX to be angled in many directions. The base of the mount is simply magnetically attached to the ferromagnetic surface, allowing easy installation.
Protect your TRX Strain Gauge Sensor Display with this leather and plastic protective case. The case allows full operation of the TRX while it protects the TRX from mud, dust, chemicals and splashed water.
