itsensor RGB200B Litemeter 420 Temperature Sensor User Manual
GENERAL DESCRIPTION
The LITEMETER 420 (LM1 420) is a calibrated cell temperature compensated with
strictly selected electronic components to ensure maximum precision.
His output signal is 4-20 mA to ensure reliability and a continuous signal
that testify a correct working.

CONNECTIONS
The connector is a 3 pin M8 standard. The male connector is not included, but it can be found in commerce: anyhow, if you desire it you can order it to us.
The IP67 3-pin circular female connector carries all the signals from the LM-420 as in Tab. 1 and Fig. 1, that shows a front view of the female connector wired to the sensor (or a back side view of the male connector):
| # | Name | Description | Loose pins |
|---|---|---|---|
| 1 | – | – | |
| 2 | – | – | |
| 3 | SUPPLY +Vin | Power supply input, + 9…30Vdc – See tab. 2 | Blue |
| 4 | I out (-) | Current Output ( – ) | Black |
The compliance voltage depends by the burden resistor (datalogger input impedance) with the relation: voltage = 8 + impedance*0.02
The voltage supply has to be equal or greater than compliance voltage.
Verify the input impedance of your DataLogger. Here below a table given to see DataLogger compatibility:
| Input burden [Ohm] | Min. supply voltage [V cc] |
|---|---|
| 20 | 8 |
| 100 | 10 |
| 150 | 11 |
| 250 | 13 |
| 500 | 18 |
| 1000 | 28 |
MEASUREMENT
The signal can be read with a amperometer placed in series to the output pole of the instrument, or with a datalogger with a 4-20 mA input.
CALIBRATION
It is recommended to calibrate this instrument after the first year of use and
successively, each three years.
Some “inclusions” may be present and clearly visible into the protective
encapsulation resin. This is due to the resin coating process and do not
affect overall performance and/or accuracy.
