The PT100 and PT1000 are thermal resistance temperature and humidity sensors with LCD display. Working in the industrial environment of -40 ° C ~ +85 °攝氏度 (host range, not an external sensor range), the acquisition temperature range is -200 ° C ~ +200 °攝氏度, display accuracy of 0.1 °攝氏度; The overall accuracy is 0.3 °C. By connecting our thermal resistance sensor with our RS-485 repeater, we can connect 32 PT100 and PT1000 thermal resistance acquisition modules to the same network up to 255, and the maximum communication distance is 1200 meters. The PT100 and PT1000 RTD sensors can also be combined with the 8052NET to form a TCP/IP temperature acquisition network for remote acquisition of temperature.
Detailed Description:
PT100型, PT1000 is a new type of thermal resistance temperature sensor acquisition module (without PT100, PT1000 temperature sensor, need to purchase separately). It can be used to collect the temperature of two channels on the spot. At the same time, the RS-485 bus serial communication interface can be used to connect with the environment monitoring host or other industrial control host conveniently.
Working at -40 ° C ~ 85 °攝氏度 (host range, not an external sensor range) industrial grade PT100, PT1000 thermal resistance acquisition module. There are two kinds of display modes: WD series without LCD display (PT100型, PT1000) and LM series with LCD display. The acquisition temperature range is -200 °C ~ +200 °C, the display accuracy is 0.1 °C; the comprehensive precision is 0.3 °C.
The PT100 and PT1000 RTD acquisition modules can be connected to the RS-485 local area control network via an isolated 485 communication interface. RS-485 allows up to 32 PT100 and PT1000 RTD acquisition modules to be connected to the same bus. However, if Link-Max RS-485 repeater is used, 為止 256 PT100 and PT1000 RTD acquisition modules can be connected to the same network, and the maximum communication distance is 1200m. Before installing the PT100 and PT1000 RTD acquisition modules into the network, configure them. First, the baud rate of the module should be set to match the baud rate of the network. At the same time, the PT100 and PT1000 RTD acquisition modules should be set to different addresses to prevent the address conflict of each PT100 and PT1000 RTD acquisition module.
After the PT100 and PT1000 RTD acquisition modules are correctly connected, the host issues a read data command to enable the PT100 and PT1000 RTD acquisition modules to send data back to the host. The data in the PT100 and PT1000 RTD acquisition modules is updated every second and the display data of the LCD display is updated periodically (LM series only).
The WD series is used where there is no need to display temperature, such as an outdoor ATM cabinet, which is a DIN rail mounted enclosure. In addition to temperature acquisition, the LM series can also preset the upper and lower alarm values of the temperature. When the environmental parameters exceed the set value, the buzzer in the main engine immediately sounds an alarm.
PT100 and PT1000 RTD acquisition modules are all-digital PT100 and PT1000 RTD acquisition modules with wide application prospects. Using this module makes temperature monitoring very easy. The PT100 and PT1000 RTD acquisition modules can be connected to two-wire, three-wire, four-wire PT100 and PT1000 thermal resistors. When three-wire four-wire is used, the module can effectively compensate the line resistance. Making the length of the cable does not affect the acquisition accuracy. The module is widely used in environmental monitoring systems, power systems and industrial automation, and has excellent cost performance.
The PT100 and PT1000 RTD acquisition modules can also be combined with the 8052NET to form a TCP/IP temperature acquisition network for remote acquisition of temperature.

NTC Temperature Sensor
What Is The NTC Temperature Sensor? NTC temperature sensor is an thermistor after the wire welding, encapsulate into a different probe and then use an epoxy seal. The temperature sensor retains all the features of the thermistor. After the optimization of the injection and cooling stages, will be made into a complete product, mass production is a continuous cycle of this processing step produced.
thermistor sensor probes and components
熱敏電阻 (negative temperature coefficient) sensor probes (OVERMOLDED PROBE, closed end SST tube; Silicone Foley Catheter; epoxy sealed, Nickel plated brass tube) /components (Cable & connector) suitable for various applications and industries. Our THERMISTOR probes and components are suitable for temperature sensing applications such as surface temperature detection, air-gas, electrical appliances, power supplies, HVAC/refrigeration systems, liquids, medical treatment, and monitoring.
What is thermocouple sensor?
The appearance of various thermocouple sensor probes is often very different due to needs. However, their basic structures are roughly the same, usually composed of main parts such as a thermode, an insulating sleeve protection tube, and a junction box, and are usually used in conjunction with display instruments, recording instruments and electronic regulators.
