Product introduction
WDL small pull rod type electronic ruler (alias: resistance ruler, potentiometer, displacement sensor) principle: Potentiometer principle, all sensors for position measurement type, used to adjust the system (control system) and measurement system, direct measurement of displacement and length, output DC voltage signals, can also be through the built-in or external V/A transmitter module to convert signals into standard 0-5V, 0-10V or 4-20mA DC signals, Control requirements can also be transmitted remotely. WDL small drawbar electronic ruler (alias: resistance ruler, potentiometer, displacement sensor) Output displacement change: 0- given input operating voltage (changes with displacement).
Output type:
Resistance output type (potentiometer) : 5kΩ,
Voltage output type (external/built-in module) : 0-5V, 0-10V,
Current output type (external/built-in module) : 4-20MA (two-wire system, three-wire system),
Digital signal (external/built-in module) : RS485,
