Description

The TR150 Portable Strain Display Load Cell/Force transducer readout is a microprocessor based portable instrument designed to interface with any full bridge sensor with an output sensitivity of up to 50mV/V. Bridge resistances from  85Ω upwards can be used with the TR150.

Configuration and calibration of the TR150 is achieved using the front panel push buttons to navigate through a very simple menu structure.

Features

• Powered by 2x AA internal batteries
• 7½ Digit Display with battery low, peak, trough, net & shunt calibration indication
• Compatible with most Strain Gauge Based Sensors
• Dual Range Facility
• Optional RS232 Communications
• Battery life of 5000 hours in low power mode with 350 ohm bridge connected
• Auto sleep facility
• Robust Construction – Sealed to IP65

User functions available on the TR150 include:-

• Range Selection
• Display Hold/Freeze
• Gross/Net indication selection
• Peak Hold selection
• Trough Hold selection
• Shunt Cal check

The TR150 is powered by two internal non-rechargeable AA alkaline batteries. The display provides the excitation voltage for the load cell, or strain gauge, and provides a programmable reading from the returned mV/V output.

Sensor Connections

The standard sensor connection is a 5 pin 723 series Binder connector. The sensor connector is also used as a charging socket, when the re-chargeable alkaline battery option has been ordered, the wiring for this is detailed below:-

PIN 1 +ve Excitation
PIN 2 -ve Excitation, -ve Charge Input
PIN 3 +ve Signal
PIN 4 -ve Signal
PIN 5 +ve Charge Input
