Description
Miniature insulated chip NTC thermistor mounted in a stainless steel housing with brass collar for sealed mounting and twin PVC isulated lead wire connection.
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 for wire-to-wire or wire-to-board
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
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
