2-8a Model
One of the variety of the 2-8 model. It applies to measure temperature of solid items by putting it on a surface. It installs on the pipe using a metal clamp. It's recommended to install it on thermal paste to ensure better thermal conduction and to cover the probe by thermal insulation to avoid effect of environmental temperature. The 4-20 mA / RS485 transducer (T-bus/ModBus protocol) can be ordered separately in Z67 enclosure with a cable gland and connect it to the probe cable.
