Thermohead Type
   Temperature Sensor Accepted       
   Your choices are...         
   Thermocouple       The junction of two dissimilar metals that has a voltage output (Seeback Potential) proportional to the difference in temperature between the hot junction and the lead wires (cold junction). 
   RTD (Resistance Temperature Detector)       Resistance Temperature Detector (Standard or Precision). Resistive Temperature Detectors operate on the principle that the electrical resistance of a metal conductor changes as a function of temperature. RTDs provide an accurate, stable and repeatable means of absolute temperature measurement. 
   Other       Other unlisted, specialized, or proprietary configuration such as thermistors or solid-state style sensors.

Physical Specifications
   Terminal Block      Typically, thermoheads include an integral terminal block for connection with the temperature sensor.
   Your choices are...         
   None       The thermohead is not equipped with a terminal block for sensor connections. 
   Single Element       The thermohead is equipped with a single element terminal block. 
   Multi Element       The thermohead is equipped with a multi element terminal block. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Material      Many material configurations are possible for thermoheads; the listed options represent the most common and typical stock products available. Material consideration should be discussed with the manufacturer for specific applications.
   Your choices are...         
   Cast Iron       The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon and/or carbide are dispersed. 
   Aluminum       A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. 
   Stainless Steel       Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings. 
   Steel       A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content. 
   Plastic       One of many high-polymeric substances, including both natural and synthetic products, but excluding the rubbers. 
   Other       Other unlisted, specialized, or proprietary material. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
