Note
• Other R25 values and tolerances available upon request
FEATURES
• Fast time response for fluid immersion
applications
• Reduced thermal gradient, due to the use of
small tip dimensions and thin isulated wire
• Sensor for permanent contact with water or
other liquids
• Compliant to RoHS Directive 2002/95/EC
APPLICATIONS
Immersion sensor used for temperature measurement,
sensing and control in:
• Water boilers
• Heating systems
• Chiller systems
• Water and used water systems
• Water and oil tanks
• Consumer appliances, Coffee machines
• Industrial appliances
• Solar heating systems
DESCRIPTION
Miniature insulated chip NTC thermistor mounted in a
stainless steel housing with brass collar for sealed mounting
and twin PVC isulated AWG#30 lead wire connection.
MOUNTING
• The sensor can be mounted by means of a sealing O-ring
and screw
• The end wire can be soldered, or crimped to a connector
• Optional connector for Wire-to-Wire or Wire-to-Board
connections
• The contact with liquid should stay below the brass collar
(see Fig. 1 for mounting example)
• Not intended for corrosive or high acidic liquids
