Two Terminal Temperature to Current Transducer. This kit provides the necessary components, including the new aluminum pm3911, to build a replacement temperature sensor that can be directly substituted for the original temperature sensors that were used on the above kits.
Now that the probe is electrically attached to the cable, it is necessary to mechanically secure the probe and wire into the sensor housing. Your temperature sensor is now ready to be calibrated and put into use.

Thermometer With Meter Output. To begin the assembly it will be necessary to datasheett the old sensor by cutting the existing cable approximately 6 inches from the existing sensor. The Heathkit part number of the module was typically a or a Note 1 C1 determines proportioning frequency f. V z e Shunt regulator voltage. Follow the calibration instructions for your particular kit. Y Internal stable voltage reference.
Original Heathkit sensor top and new replacement unit below. Lm39911 remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason. All of the components have already been mounted on the board and the board has been tested.
ID Adapter Board
The circuit was taken directly from the National LM datasheet. Y Output can drive loads up to 35V. Sealing the assembled temperature sensor in the tube. Letting it stand overnight is best. Assembled and Tested Temperature Sensor.
I L e Low temperature output current A. D T e Meter temperature span K. Output goes negative on. Note 3 Either V b or V a can be ground. Ground Referred Centigrade Dataheet. T O e Temperature for zero output K.

Temp Sensor board attached to old cable end. V z e Shunt regulator voltage use 6 The LM is a highly accurate temperature measurement. Select I Q s R1. The 0 01 in the above and following equations is in units of V K or V C and is a result km3911 the basic 0 01V K sensitivity of the transducer. D T e Temperature span K.
All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal. The input bias current is low and relatively constant with. Y Internal op amp with frequency compensation. V Z e Zener voltage V.

Stand the probe on end and allow all of the silicon seal to cure completely. Y Uncalibrated accuracy g 10 C.
The LM is available in two package lk3911 a metal can. T O e Meter zero temperature K. Selected as for meter thermometer except T O should.
Y Can be calibrated in degrees Kelvin Celsius or. V O e Full scale output voltage s 10V.
The 0 01 in the above and following equations is in units of V K or V C. If you no longer have the original manual, we have replacement manuals available for some kits at: The LM uses the difference in emitter-base voltage of. I H e High temperature output current A. This will take a couple of hours.
Unfortunately the LM is no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves. An active shunt regulator is connected across the power. The LM was a single chip that would output a 10 mV change for every degree of change in temperature. The output voltage of the LM is directly proportional to. This should create a water-tight seal.
Set output to read C. Trims out initial zener tolerance. LM to the temperature souce The LM is rated for.
