Configuration & Option Sensor Coil Anti-Rotating Detection (Mold Circuit) TRG Meter (Flame-Proof) TRG Panel Meter (Option) TRG Alarm (Option) TRG Converter (Option)5

TRG Convertor TRG Signal is converted to 4-20(mA) or 1-5(V) which realizes centralized control. Flam Proof Explosion (d2G4) is available as option.

TRG Singnal With Anti-Rotating Detection (TRG Model : M, R) Diode Commutation, 350mVDC to Full Scale Without Anti-Rotating Detection (TRG Model : L, G) Raw TRG Signal AC1V to Full Scale Frequency < 3kHz10

Wiring to Outer Divices, TRG-Panel Meter, Alarm, and Convertor Wiring : Single Core Shielded Signal Wire 1.25mm2 or BiggerCore to G1 Terminal, Shield to G2 Terminal

In case Double Core Wire is used,Core to G1 Terminal, Shield to G2 Terminal

Shield must NOT be Grounded Keep Away from Power Cable11

Other factors to vary TRG Indication Over Loading Since TRG is sensing magnetic field generated by amperage on rotor, indication varies depending on loading. i.e. Flow Rate, SG, Viscosity, Ambient Temperature Devises in TRG meter is affected by temperature but indication varies no more than 0.1 scale. 13
