1. Safety instructions
The equipment conforms to safety regulations
for electrical measuring instruments and control
and laboratory equipment as per DIN EN
61010, part 1.
• In order to avoid permanent damage to the
built-in Pt100 sensor, never exceed the
maximum temperature of 150°C.
• Never expose the PVC grip or the connect-
ing cable to temperatures above 80°C.
2. Description
The temperature sensor Pt100 with measurement terminal is used for measuring temperatures ranging from -50°C to +150°C. It is used
in conjunction with the 3B Netlog
50/60 Hz) (1000540) resp. 3B NETlog™ (115 V,
50/60 Hz) interface. Once connected, the sensor is automatically detected by the interface.
The temperature sensor is designed for measuring temperature in the copper piping of heat
pumps (1000820 or 1000819). The tip of the
thermocouple has a suitably shaped copper
clamp for pipes with a diameter of 6 mm.

• The packaging should be disposed of at
local recycling points.
• Should you need to dispose of the equip-
ment itself, never throw it away in normal
domestic waste. Local regulations for the
disposal of electrical equipment will apply.
