WP162 small pressure collector adopts MEMS monocrystalline silicon pressure sensor chip to be packaged in a specific shell. The pressure sensor and the conversion circuit are integrated to form a small special pressure sensor. It has a small size, high measurement accuracy, good reliability,
WP-9000 series thermal resistance temperature transmitter (output loop power supply), input the field thermal resistance temperature signal, isolate and convert the linear (4-20) mA signal to the temperature and output it to the control system or other unit combination meters. Some signal receiving devices have their own 24V power supply. Generally, the output of the temperature transmitter is an active signal, and power conflicts will occur when connected. Using output loop power supply will avoid power conflicts and achieve signal isolation.
WP-8000-EX series thermocouple isolation safety barrier, receives thermocouple signals or other millivolt signals in hazardous areas on site, after isolation and linearization, it is converted into linearized DC signals and output to the control system or other in the safe area Unit combination meter. Intelligent thermocouple isolation safety barrier. The thermocouple type and measuring range can be configured and set.
At present, most of the current and voltmeters on the market use simple rectification and averaging circuits to complete the measurement of AC signals. There are large theoretical errors. Therefore, these meters can only be used for standard undistorted sine waves when measuring the effective value, if it is a non-sine waveform Or the measured result of the distorted sine wave does not match the actual value of the signal. The true effective value transmitter adopts the averaging technique of signal integration after squared. It is used for accurate measurement of standard sine wave or aperiodic, non-sine wave and superimposed DC level of various noises, without considering waveform parameters and distortion. These performances are The average value measuring instrument cannot be realized.
The switch input isolator receives the signal from the switch or proximity switch, and transmits it to the control system or other intelligent instruments through a relay with changeover contact output through isolation.
