V O e Full scale output voltage s 10V. Sealing the assembled temperature sensor in the tube. All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal.
Select I Q s R1. Thermometer With Meter Output. Selected as for meter thermometer except T O should. The remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason.
The output voltage of the LM is directly proportional to. To begin the assembly it will be necessary to remove the old sensor by cutting the existing cable approximately 6 inches from the existing sensor. Two Fatasheet Temperature to Current Transducer.

Note 1 C1 determines proportioning frequency f. Stand the probe on end and allow all of the silicon seal to cure completely.
Make certain that there is a good attachment of the silicon seal datashert the existing cable. If you no longer have the original manual, we have replacement manuals available for some kits at: The 0 01 in the above and following equations is in units of V K or V C and is a result of the basic 0 01V K sensitivity of the transducer.
V Z e Zener voltage V.
The LM was a single chip that would output a 10 mV change for every degree of change in temperature. Assembled and Tested Temperature Sensor. LM to the temperature souce The LM is rated for.
Your temperature sensor is now ready to be calibrated and put into use. Letting it stand overnight is best.
Y Internal stable voltage reference. The 0 01 in the above and following equations is in units of V K or V C. The input bias current is low and lm39111 constant with.
ID Adapter Board
The LM uses the difference in emitter-base voltage of. V z e Shunt regulator voltage use 6 T O dztasheet Temperature for zero output K. This will take a couple of hours. Y Uncalibrated accuracy g 10 C. This should create a water-tight seal.
Unfortunately the LM is no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves. The Heathkit part number of the module was typically a or a Note 3 Either V b or V a can be ground.
