Gefran indicators
40B indicator displaying 'Hi or Lo, Er' when connected to a 3.33mV/V strain gauge.
This is usually an indication that the input sensor signal is out of range. Note: a 'calibration'/adjustment is always required when new pressure sensors are connected to indicator.
4-wire solution
Can I use a 4/40T indicator to supply a MK4 linear transducer?
No. The MK4 transducer draws 70/90mA, but the maximum current supplied by the 4/40T is 50mA at 24V.
40BX-X-24-X-X-X-X-X may be used.
Can I use a 4/40T indicator to measure the output of a LTM displacement transducer?
Yes, but only the special version: 40TX-X-0.1/10-XX-XX-X-X-X R77
Gefran indicators: Do you have a display that can indicate more than one zone?
(thermocouple, resistance sensor, voltage and current)
Gefan indicators: How can I simulate a sample weight or pressure?
A sample weight/pressure can be simulated with a mV or analogue signal from a signal generating device.
Gefran indicators: What does resolution mean?
In this case, the resolution is an indication of the smallest quantity that can be measured.
