1-Wire Temperature Sensor - 1.5 m

Product description

Digital 1-Wire water-resistant temperature sensor is based on the DS18B20 chip covered by a stainless steel cap. Each sensor features an RJ45 plug and can be connected to any Unipi controller with the 1-Wire bus. A single bus supports up to 15 sensors (the response time can be higher in such connections). The number of sensors connected to a single controller can be further increased by utilizing corresponding patch cords or the 8-port with an integrated DIN rail holder.

Several hubs can be connected in a cascade. More info about connecting 1-Wire sensors can be found on this link. 

Sensors are universal, their temperature range is -55 °C/+85 °C (-67 °F/+185 °F).

Sensor dimensions

Practical use examples

• measuring indoor/outdoor temperature for the purpose of heating switching
• measuring the temperature of liquid stored in tanks (for more precise measurements it is possible to use more sensors located in several levels)
• measuring liquid transport lines temperature
