Technical requirement

The basic function of the LVDT Transmitter LTM-6A is to convert information into a form that is easy to transmit and process, requiring information to be undistorted, not delayed, etc. During the conversion process, there are certain requirements for the linearity, input and output impedance matching, and isolation of the converter:

(1) Linearity: It is required that the output signal of LVDT Transmitter LTM-6A has a good proportional relationship with the input signal.

(2) Input impedance and output impedance: The input impedance and output impedance of the signal converter must match the input and output instruments in order to achieve high conversion accuracy.

(3) Isolation characteristics: The input circuit, output circuit, and power circuit should be isolated from each other at DC potential, and the grounding points of the input and output circuits should be separated to improve anti-interference ability.

Debugging steps

1. Confirm the power supply voltage and signal output range of the LVDT Transmitter LTM-6A. In general, the transmitter of LVDT displacement sensors requires a power supply voltage of 24V DC, and the signal output range needs to be set to the corresponding voltage or current range.

2. Connect the sensor and LVDT Transmitter LTM-6A. Connect the three cables of the sensor to the corresponding ports of the transmitter, usually to the input ports of the transmitter.

3. Confirm that the connection is correct. Confirm that the connected cable matches the ends of the sensor and transmitter, ensuring that the cable connection is secure and there are no loose or detached contact points between the sensor and transmitter.

4. Perform zero calibration. Zero the measurement output of the LVDT sensor without stress. Usually, it is necessary to adjust the zero potentiometer of the transmitter until the output voltage or current is zero.
