Gefran 2400: Strain Gauge/ Temperature Indicator w. alarm
Stock Code:
SKU: product options
The high resolution fast Gefran 2400 indicator, 96x48 (1/8 DIN) format, for measurement and alarming of pressure (direct and differential), displacement, force, temperature, process variables measured by amplified sensors.
CALCULATION CAPACITY
- Compare input variables, calculate the engineering unit, calculate flow rates, ratio, etc.
- Results can be used as process value / alarm setpoint / retransmitted output
TWO CHANNELS FOR MEASUREMENT / WEIGHING
- Two main inputs let you simultaneously make two rapid acquisitions with a single instrument.
- The instrument can supply up to 6 load cells in parallel
- Resolution: 100.000 points
EASY CALIBRATION
- Just enter the sensor label data
- You can always calibrate conventionally by using the menu.
The sampling valvue (80% standard) can be set for a strain- gauge
