M-system B3FR User manual

Brand: M-system

Model: B3FR

Type: User manual

M-System B3FR is a highly accurate and versatile RTD transmitter designed to measure and transmit temperature signals from RTD sensors. It features a wide temperature measurement range, configurable input types, and a variety of output options, making it suitable for various industrial applications.

The B3FR's input configuration allows users to select the type of RTD sensor being used, including Pt100, Ni120, and Cu10. The coarse and fine adjustment options provide precise calibration for accurate temperature readings. The transmitter's burnout protection ensures reliable operation even in the event of sensor failure.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered

speciﬁcations, therefore you usually do not need any cali-

bration.

Formatchingthesignaltoareceivinginstrumentorincase

ofregularcalibration,adjusttheoutputasexplainedinthe

following.

■ HOW TO CALIBRATE THE OUTPUT SIGNAL

Use a signal source and measuring instruments of sufﬁcient

accuracy level. Turn the power supply on and warm up for

morethan10minutes.

1) ZERO:Apply0%inputandadjustoutputto0%.

2) SPAN:Apply100%inputandadjustoutputto100%.

3) CheckZEROadjustmentagainwith0%input.

4) When ZEROvalue is changed, repeatthe aboveproce-

dure1)–3).

■ CALIBRATION

Warmuptheunitforatleast10minutes.Apply0%,25%,

50%, 75% and 100% input signal.  Check that the output

goes over 100% (below 0% with downscale protection)

due to burnout function. Check leadwires in such a case.
