Replaces all previous types: LTT420M, STT1000SA, TS334 and TS334S
Clamp-on temperature measurement.
Quick configuration with simple windows software by
connecting the PC´s USB port directly to the device´s M12 connector (4 pole).
Supply voltage : 7 - 34VDC
Measuring range °C : -40 til 180 °C ( Configuration resolution = 0,1°C (IEC 751)
Output in transmitter-mode : I - Load = 4-20 mA (effect of variations in supply voltage≤ 0,1µA/V)
Output in switch-mode : I - Load off = 3,40 mA / I load on = 34,00 mA ± 1%
Ambient temperature coefficient : ≤ ± 0.002 % af F.S. / °C (from -30 to +80 °C)
Direct invertet function : Optional
Hysteresis from switch on to off : Free configurable by 0,1°C resolution. (symmetrical around set point´s value, minimum value = 0,2°C)
Temperature sensor : PT100 1/3 din B curve (accuracy in °C ≤ ± ( 0,1 (measured temperature x 0,0017))
Accuracy on electronic unit : Better than ± 0,1°C according to the IEC751 standard.
Calibration facilities : With PC connected, Off set and Gain can be adjusted. ( with Off set = 0,00 °C and Gain = 1,0000 the IEC 751 standard is followed).
2 color LED indicator (green/red) : LED in side of the house indicate the device phases during operation.
Physical dimentions mm : B x H x L = 22 x 30 x 38
