IoTKey® Transmitter WLT 310

IoTKey® WLT 310 Transmitter

The WLT 310 is a wireless LoRa (Long Range Radio) transmitter designed for various industrial applications and capable of sending data over extremely long ranges. The WLT 310 is a LoRa Alliance Certified™ product.

The smart transmitter’s application parameters are configurable Over-the-Air (OTA) and it continuously measures process values. It is a low-energry transmitter with a battery life of several years, the LoRa technology has zero operating costs, and no 3G/4G network is needed.

  • Inputs: Pt100, Pt1000, thermocouples, humidity sensor, 0-10 VDC and 0/4-20 mA
  • Power supply: Lithium battery 3.6 VDC or 12/24 VDC
  • LoRa transmission technology has a 15 km range outdoors, and the signal also transmits well indoors and even below ground
  • Freely configurable OTA measurement intervals and alarms
  • Environmental temperature range –40...+80 °C, depending on the battery type.

What is LoRa?

LoRa is the acronym for Long Range Radio. Thus, a LoRaWAN™ is an LPWAN (Low Power Wide Area Network) specification designed for wireless, battery-operated “Things” (devices) in regional, national or global networks – as part of the Internet of Things (IoT). LoRaWAN targets key requirements of the IoT, such as seamless interoperability among smart Things, without the need for complex local installations. It gives users, developers and companies the freedom to expand the IoT.
