Gefran 4T 72 Indicators
Temperature Indicator with configurable Input. Input type and the function of the keys on the faceplate are software selectable.
Microprocessor based indicator in 72x36 format manufactured with SMT. The instruments have a lexan membrane faceplate (guaranteed to IP65) which has 3 keys, a 2, 3 / 4-digit display. The input signal can be selected from a wide range of sensors:
- Thermocouples of type J, K, R, S, T, B, E, N, L GOST, U, G, D, C
- Resistance thermometers Pt100, Pt100J (japanese standard) 2 / 3 wire
- PTC and NTC themistors
- Linear inputs 0 to 60/12 to 60mV, 0 to 20/4 to 20mA, 0 to 10/2 to 10/0 to 5/1 to 5/0 to 1/0, 2 to1V
Features:
- AC voltage, AC current direct input on instrument terminals
- Tamper proofing and access limitation, password protected
- Configurable via PC with "Winstrum" software
- Labels to customize measured physical unit
- Connect your input device (4-20mA transmitter, loadcell…) directly the 24V/10V on-board supply
- Reset maximum/minimum register or "zero" the input via keys on the faceplate
- Recall minimum/maximum values via keys on faceplate
- On-board 24Vdc source for loop powered transmitter inputs
The selection is made using the faceplate keys and correct input contact. No external shunt or adapter is required. The programming of the instrument is made easy by grouping the parameters in function blocks and by a simplified data entry menu.
The configuration can be simplified even further using the PC programming kit made up of a connection cable and a menu guide program that runs win windows. A configurable personal software protection code (password protection) can be used to restrict the levels of editing and displaying the configuration parameters.
Other indicator input options:
- 4A series: AC current/ Voltage Indicators
20mAac, 50mAac 200mAac, 1Aac, 5Aac, 2Vac, 20Vac, 200Vac, 500Vac - 4B series: Strain Gauge, Potentiometer, Melt-Pressure Indicators
