I L e Low temperature output current A. 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. All of the components have already been mounted on the board and the board has been tested. Output goes negative on. Note 1 C1 determines proportioning frequency f. I H e High temperature output current A. The input bias current is low and relatively constant with.
Set output to read C.
Unfortunately the LM is no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves. The remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason.
V O e Full scale output dstasheet s 10V. Make certain that there is a good attachment of the silicon seal to the existing cable.
The Heathkit part number of the module was typically a or a This will take a couple of hours. Two Terminal Temperature to Current Transducer. D T e Meter temperature span K.
V z e Shunt regulator voltage use 6 Select I Q s R1. Y Uncalibrated accuracy g 10 C. Note 3 Either V b or V a can be ground. If you no longer have the original lm911, we have replacement manuals available for some kits at: This should create a water-tight seal. Follow datashet calibration instructions for your particular kit.
All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal.

T O e Temperature for zero output K. T O e Meter zero temperature K. The LM is a highly accurate temperature measurement.
The LM was a single chip that would output a 10 mV change for every degree of change in temperature. I M e Meter full scale current A. Selected as for meter thermometer except T O should. Your temperature sensor is now ready to be calibrated and put into use.
Original Heathkit sensor top and new replacement unit below. Sealing the assembled temperature sensor in the tube. Y Internal op amp with frequency compensation. Y Output can drive loads up to 35V. Stand the probe on end and allow all of the silicon seal to cure completely. V Z e Zener voltage V. Y Can be calibrated in degrees Kelvin Celsius or.
D T e Temperature span K. Satasheet With Meter Output. Assembled and Tested Temperature Sensor. The circuit was taken directly from the National LM datasheet. V z e Shunt regulator voltage. Trims dqtasheet initial zener tolerance.

This kit provides the necessary components, including the new aluminum tube, to build a replacement temperature sensor that can be directly substituted for the original temperature sensors that were used on the above kits.
The output voltage of the LM is directly proportional to. 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.
