Sanitary Temperature Sensor Specifications Include:
316L stainless steel process wetted surfaces with surface finishes
of 32 microinches or better.
Probe lengths of 3, 4, 5 or 6 inches available from stock, other lengths available
as special orders.
Sensor Output is a 4-wire, 100 ohm, Class A, Platinum RTD meeting
the requirements of IEC 60751.
These sensors can be used with 2-wire or 3-wire systems see information below.
Insulation resistance: 100 megohms minimum at 100 VDC.
Thermal response time of less than 2.5 seconds in water flowing
at 3 ft/sec (63% response).
This Sanitary Temperature Sensor containes a PT100 Platinum RTD element and is designed for use in Food, Dairy, Beverage and BioPharmaceutical Clean-In-Place (CIP) type applications. The sensor includes a
1½" 16AMP process connection that conforms to ASME BPE-2007 for easy installation using industry standard
gaskets and clamps. Standard Duty sensors are available with ¼"
diameter probes, and Heavy Duty sensors are available with a stepped 3⁄8" to
3⁄16" diameter probe. This sensor is provided with a 120" long, 4-conductor, #26AWG
stranded nickel plated copper, PFA insulated and jacketed cable with
a strain relief for convenient connection to control or monitoring
Food process hygienic temperature sensors can be used to aid food safety inspection compliance and verification of time temperature control. Combined with a chart recorder model CTXL you can temperature monitor a CCP ( Critical Control Point) or sanitation time and move toward a HACCP (Hazard Analysis Critical Control Point) compliance plan.
In addition to the standard 1½-16AMP process connection, these can be provided
in the following sizes and styles:
Model Number Code
1" and 1½"-16AMP
If you need a process connection that is not listed above, please contact our sales department for availability.
These sanitary sensors are supplied standard as 4-wire assemblies with two
red wires and two white wires. When used in 3-wire applications,
cut off one white wire making sure that it will not contact any terminals
or metal surfaces (note: twisting the two white wires together will reduce
the lead wire resistance on one side of the sensing element by half
adversely affecting the accuracy of the reading).
When used in 2-wire applications, cut off one white wire
and one red wire (note: in 2-wire applications, twisting the two
same-colored wires together at the terminals will not adversely
affect your sensor accuracy since both wires will be affected by
the reduction in resistance).
These sensors are also
available in Thermistor
and Thermocouple styles to accommodate any process input requirement.
