Models 110 and 120
Field Cuttable or Breakable Thermocouples
by Ultra

Designed for applications where a threaded male fitting is required for mounting in tanks, stacks, pressure vessels. Stocking “cuttable” and "hand-breakable" sensors can reduce inventory and down time as the 110 can be easily cut and the 120 can be broken, to the required length in the field and a fitting can be installed in a matter of minutes

Model 110 is designed to be used with optional connector or spring-loaded fitting

Model 120 - Hand-breakable thermocouple

 

 

Model 452
Spring Loaded Sanitary Thermocouple
by Ultra

Ultra, has expanded on its already successful model 451. The model 452 is designed to be used in applications where spring loading is desired for fast temperature response when used in a sanitary thermowell.
Model 452 features no exposed threads where bacterial growth or contamination can be a problem. Multiple configurations are possible, including dual sensor versions for back up and comparative measurement, options for protection heads and temperature transmitters locally mounted, and different sanitary cap sizes to match up with different thermowells.
In addition, multiple surface finishes can be specified on the external probe housing.

Model 3142B
Sanitary Flush Mount Tank
Thermocouple
by Ultra

Ultra has developed a unique flush mount,
tank temperature sensor for use in sanitary applications. The model 3142B is designed to mount flush to the wall of a tank. It is completely non-intrusive and will not interfere with any wipers or mixers in the tank.

The Model 3142B is a non-intrusive design – ideal for where mixers or wipers would interfere with typical insertion type sensors

Clean-in-place (CIP) / Steam-inplace (SIP) – dual o-ring design for sealing
316L stainless steel construction – Welding spud provided with assembly
Ideal for retrofit to existing tanks
Teflon insulation provides true process temperature measurement, by eliminating potential false reading from tank wall
Removable sensor – allows process to remain sealed during sensor replacement or calibration
Patent pending design

Model 3226A
Food Piercing
Thermocouple
by Ultra

Ultra manufactures temperature sensors designed specifically  for use in meat processing where precise temperature measurement is required during the cooking, smoking and curing of the product.

The model 3226A is of 316L stainless steel sheath construction with piercing tip
 Available in RTD or thermocouple with separate shielding
Extruded Teflon wire insulation – Resists moisture – Increased wire strength
Heavy walled sheath construction –Resists breakage
Crimped transition with strain relief – Resists wire separation
Meets 3A sanitary finish standards
