Product details



The WNK6T intelligent temperature transmitter is a high-performance product in the temperature series instruments of Anhui Wanke Company. It converts signals from thermal resistors, resistive sensors, thermocouples, or voltage sensors into standard signals.

The transmitter adopts dedicated integrated circuit digital technology to achieve good accuracy and signal consistency. Each transmitter undergoes ambient temperature characterization at the factory to ensure high accuracy and minimal drift over a wide range of operating temperatures.

The transmitter is easy to install on site and can be integrated with temperature sensor components or installed away from the sensor. The sturdy casing comes with a globally compatible conduit connection port, and the dual chamber aluminum casing ensures the use of the transmitter in hazardous areas.



·Numerical accuracy: ±0.01℃,Pt100Thermal resistance input

· 24Position model-The digital converter is equipped with environmental temperature compensation and has outstanding measurement performance throughout the entire working range

·Transmitter-The matching characteristics of the sensor are easy to use, which can reduce the interchangeability error of the thermistor sensor and improve the measurement accuracy75%

·The dual chamber structure shell ensures excellent reliability of the transmitter in high temperature, corrosive, and RF interference environments

·Integrated transient protector to prevent damage to the transmitter caused by transient currents introduced by the circuit

·Thermal resistance electromotive force correction - detecting and eliminating electromotive force errors. This error is caused by a small voltage signal generated during thermal resistance measurement

·Independent parallel alarm circuit, which can provide an independent and backup alarm output in case of circuit board or software failure

·Self calibration: By comparing dynamic measurements with highly stable and accurate internal benchmarks, the analog-to-digital conversion circuit automatically updates each temperaturePerform self calibration



·The factory sets the output mode according to user requirements, making installation convenient

·Integrated LCD meter head

·Special sensor input capability allows users to input special sensor parameters into the transmitter and adjust the temperature curve inside the transmitter

·HARTProtocol type transmitters can be used withHARTHandheld device,AMSEquipment management system or adoptionHARTProtocol based system for digital communication

·PROFIBUS-PABus protocol transmitters can be used withPDMFDTAMSDevice management system for communication and device management

·FFBus protocol transmitters can be used withFDTAMSDevice management system for communication and device management



·Ready to use - provides a complete set of temperature measurement components, including transmitters, sensors, extensions, and thermal sleeves, all of which have been calibrated and connected at the factoryOnce the wiring and configuration are complete, it can be directly installed and used during the process
