Product Name is (RTD MPT B)


• Low cost
• Water-tight
• Construction
• Easy to use flexible design
• Temperature range: -50~105°C
• Employs standard Pt 100 or Pt 1000 DIN platinum resistance temperature elements
• Direct temperature measurement without need of any further assembly.


MPT temperature sensor is made up of Pt 100W or Pt-1000W platinum resistance temperature detector and connection cable molded together in thermoplastic rubber insulation. The sensor can be used for direct temperature measurement in air or liquids. The connection cable can be connected to a temperature indicator for display of temperature. MPT sensor features small size, flexible vibration-proof design and completely waterproof construction. The sensor is available in either 2-wire or 4-wire designs with standard one meter long connecting cable. Extra cable is available upon request from customers. Optional stainless steel enclosures are available to protect the probe tip. 


MPT has numerous applications in various types of industries for contact type or immersion temperature measurement in air or liquids within the range of  -50 to 105°C. It can be used in chemical industries for continuous immersion in corrosive liquids e.g., electrolytic processes and for temperature measurement of hot or frosted pipe-lines. It is hygienic for temperature measurement in food industry as it does not contaminate food products. It also finds applications for temperature measurement in automobile or other vibrating machinery.  It can also be used as a sub-assembly for low temperature resistance temperature detector assemblies.
