Transmitter Input




   Reference Material       
   Your choices are...
 
      
 
   Platinum
 
     The most common metal used for RTDs - for measurement integrity platinum is the element of choice.
 
   Nickel / Nickel Alloys
 
     Very common metal used, economical but not as accurate as platinum.
 
   Copper
 
     Occasionally used as an RTD element. Its low resistivity forces the element to be longer than a platinum element. Good linearity and economical. Upper temperature range typically less than 150 degrees Celsius.
 
   Other
 
     Gold and Silver are other options available for RTD probes - however their low resistivity and higher costs make them fairly rare, Tungsten has high resistivity but is usually reserved for high temperature work.
 
   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.
   Reference Resistance      When matching probes with instruments - the reference resistance of the RTD probe must be known. These are the most standard options available.
   Your choices are...
 
      
 
   10 Ohms
 
      
 
   100 Ohms
 
      
 
   120 Ohms
 
      
 
   200 Ohms
 
      
 
   400 Ohms
 
      
 
   500 Ohms
 
      
 
   1000 Ohms
 
      
 
   Other
 
      
 
   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.
   Other Input       
   Your choices are...
 
      
 
   Analog Voltage
 
     Transmitter accepts and conditions analog voltage inputs such as 0-10 Vdc.
 
   Analog Current
 
     Transmitter accepts and conditions analog current inputs such as 4-20 mA.
 
   Resistance Input
 
     Transmitter accepts and conditions analog resistance inputs such as 0-10 Ohms.
 
   Other Sensor Input
 
      
 
   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.
   Sensed Temperature
 
     Temperature range to be sensed and transmitted.
 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
Transmitter Specifications




   Mounting       
   Your choices are...
 
      
 
   Thermohead / Thermowell Mounting
 
     Transmitters meant to be an integral part of a probe assembly. They are typically mounted within a thermohead or thermowell. The most common style are hockey puck shaped.
 
   DIN Rail Mounting
 
     Transmitter mounted on a DIN rail style rack.
 
   Board / Cabinet Mounting
 
     These transmitters are meant to be mounted within a cabinet (or rack) or be computer board mounted. They may include board connector.
 
   Other
 
      
 
   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.
   Output       
   Your choices are...
 
      
 
   Analog Current (e.g., 4-20 mA)
 
     Transmitter outputs analog current signal to represent temperature being monitored. This is the most common output style
 
   Analog Voltage
 
     Transmitter outputs analog voltage signal to represent temperature being monitored.
 
   Relay / Switch Output
 
     Transmitter is a simple switch or relay based on temperature being monitored.
 
   Other
 
      
 
   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.
User Interface




   Local Interface
