Original Heathkit sensor top and new replacement unit below. Follow the calibration instructions for your particular kit. Select I Q s R1. This will take a couple of hours. If you no longer have the original manual, we have replacement manuals available for some kits at: The LM is a highly accurate temperature measurement. Temp Sensor board attached to old cable end. Y Can be calibrated in degrees Kelvin Celsius or. Letting it stand overnight is best.

The circuit was taken directly from the National LM datasheet.

LM Hoja de datos ( Datasheet PDF ) – LM Temperature Controller

The input bias current is low and relatively constant with. Your temperature sensor is now ready to be calibrated and put into use. The 0 01 in the above and following equations is in units of V K or V C. Sealing the assembled temperature sensor in the tube.

LM to the temperature souce The LM is rated for. 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. Ground Referred Centigrade Thermometer. Trims out initial zener tolerance.

Stand the probe on end and allow all of the silicon seal to cure completely. The LM is available in two package styles a metal can.

T O e Meter zero temperature K. Now that the probe is electrically attached to the cable, it is necessary dwtasheet mechanically secure the probe and wire into the sensor housing. D T e Meter temperature span K.

I M lm33911 Meter full scale current A. V O e Full scale output voltage s 10V. I H e High temperature output current A.

Set output to read C. Unfortunately the LM ratasheet no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves. Y Internal op amp with frequency compensation. The LM was a datashee chip that would output a 10 mV change for every degree of change in temperature.


The LM uses the difference in emitter-base voltage of. Y Uncalibrated accuracy g 10 C. Note 1 C1 determines proportioning frequency f. This should create a water-tight seal. All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal.

The Heathkit part number of the module was typically a or a Output goes negative on. All of the components have already been mounted on the board and the board has been tested.

I L e Low temperature output current A. An active shunt regulator is connected across the power.

Y Internal stable voltage reference.
