Input Details
|
| The input is suitable for any full wheatstone bridge sensor and transducer excitation voltage 9.6 volts 1.0A (common to all channels). |
| Compensation |
by ± sense wires for cable connection, voltage drops and any variation in the excitation supply. |
| Load cell sensitivity |
is preset via DIL switches to 0.5, 0.8, 1.0 1.25, 1.5, 2.0, 2.5, 3.5, 5,10, 20, 50, 100 or 200mV/V. |
| Initial offset |
≤±0.15mV (15µV/V) which is cancelled during auto calibration. |
| Speed |
10 readings per second with a digital filter to reduce speed. |
| Accuracy |
is 90 days ±0.08% of reading, ±0.05% FSD (typically) |
| Drift |
is ±0.002% per degree C @ 2.5mV/V (typically) |
| Resolution |
15 bit (4.5 digits) |
| Contact inputs |
Available for auto tare, print and peak hold reset and are volt free |
Rack Mounted Load Cell Amplifiers
|
| Two versions are available to mount in the standard 19” rack |
| Version 1 (RL1) |
comprises an amplifier which is programmed via a hand held, plug in programmer. This version allows for the fitting of the 12 amplifiers. |
| Version 2 (RL2) |
comprises an amplifier which has a front panel mounted LCD display; program buttons are accessed through 2.2mm apertures in the panel. This version allows for the fitting of 8 amplifiers. |
Analogue Outputs
|
| Drive |
4-20mA up to 1Kohm and 0-10 volts up to 2mA. |
| Accuracy |
4-20mA ±0.15% of range (typically) 0-10V ±2% before calibration |
| Resolution |
13 bit (Settling time 0.25 secs to 1% of step change) |
| Isolation |
±130V RMS or DC max to analogue input or any other port. |
Data Retention/Protection
|
| Retention |
10 years for set up values, minimum of 100,000 write cycle |
| |
Protection of data and function(s) Watchdog timer giving repeat auto resets. |
| |
Impending power detection and hold off. |
| |
Keypad security and time out. |
