FA01A

Features & Applications

• Connect the wires according to the wiring requirements.

• Connect the transmitter with DC power of specified size,

• Connect the sensor, and adjust it to the corresponding zero output value (e.g. 0~10v output is adjusted to 0.000v) through the zero adjustment potentiometer when no load is installed.

• After the zero point is adjusted, load the sensor (preferably the maximum value of the measuring range), and then adjust the gain potentiometer to the corresponding value (e.g. 10.000v for 0~10v input) or to any value as required.

• After parameter adjustment is completed (calibration is preferably repeated for 2-3 times) and confirmation, disconnect the power supply.

• Seal the adjusting potentiometer screw with a coagulant such as wax or nail polish to prevent errors caused by jitter.

Description

FA01A amplifier is made of aluminum alloy casing, with imported high-performance components inside, which precisely amplifies the output signal of the sensor, stabilizes the voltage inside, supplies bridge with constant current, converts voltage and current, adapts impedance, compensates linearity, compensates temperature, etc. The mechanical quantity is converted into standard current and voltage signals for output, which can be switched between 0-10mA 0-20mA 4-20mA 0-5V 0-10V. Can be directly connected with interfaces such as PLC, singlechip, upper computer terminal and the like of automatic control equipment or computers. It has the functions of standard signal external zero adjustment and external gain adjustment, input overvoltage protection and output short circuit protection.
