Thermometer with measuring range -40 °C to 125 °C. Pipe mount make to measure pipe termperatures. IP65 coverage, power voltage up to 36V. Communication via RS485 bus using ModBus RTU or spinel protocol.
TQS4 P is an intelligent digital thermometer for outdoor temperature measuring communicating via standard industrial bus RS485 (two wires). It can measure temperatures ranging from -40 °C to 125 °C with resolution of 0.1 °C. Measured value is sent directly in °C, so the value does not have to be converted. Thermometer does not need to be calibrated, it is ready to measure right upon connecting.
Thermometer communicates on the RS485 using ModBus RTU or Spinel protocol. It can be on the same bus with other RS485 devices. One RS485 bus can have up to 32 devices (it can be even more). Both protocols are described in the documentation including examples. Spinel also has a simple ASCII format suitable for educational purposes.
Protocols can be switched easily using the ModBus Configurator software.
TQS4 thermometers are easily connected to various systems. Either to most industrial systems using RS485 bus or using an Ethernet, WiFi, USB, RS232 or other converter. We are happy to help you choosing other components of your system.
Example of connection of TQS4 thermometers to PC or PLC in different ways
Converter: Connection to the PC's COM port (RS232) is carried out using TC485 converter. USB connection can be made using SB485L converter. Ethernet can be connected to your system using convertors GNOME485 or Edgar (with power output to power your thermometers).
Power: One 12V DC power supply is suitable to power all thermometers.
Wiring: We recommend using a standard UTP cabling to connect RS485. Use one twisted pair for the RS485 and others for power to minimize the power losses.
Software: We supply Wix measuring software to measure, save and supervise all measured data from your thermometers. You can also easily embed TQS4 thermometers to your system - more options are described in the manual. We also supply Spinel.NET - Windows SDK for .NET environment (only with czech documentation).
Other option is to measure directly via the Ethernet converter / concentrator: TME Multi.
