SENSOR TECHNOLOGY
CONTACT TEMPERATURE SENSOR ALF
TECHNICAL DATA
APPLICATION
Housing colour: Housing material:
pure white, similar to RAL 9010 PA plastic (30% GF reinforced)
The ALF contact temperature sensors are used for temperature measurement on pipes, tubes or heat carriers. For better temperature transmission between the pipe and the contact sensor, the use of a heat conducting paste is recommended.
Ambient temperature: Permissible atmospheric humidity: Max. measurement current (passive):
−30 to +70 °C
max. 95% rel. humidity, non-condensing
< 1 mA
Electrical connection:
screw-type terminals 0.14 mm² – 2.5 mm²
only at safety extra-low voltage passive max. 30 V AC / 42 V DC on pipe by means of cable tie-wrap
Mounting / attachment:
Tolerances:
PT100 / PT1000
Protection rating: Protection class: Safety and EMC:
IP65
III
according to DIN EN 60730
Sensor characteristic curves:
the sensor characteristic curves can be found in the ‘Miscellaneous’ section
Please follow the EMC directives, avoid parallel routing with mains voltage-bearing wires, or use shielded wires.
