The LM is available in two package styles a metal can. The circuit was taken directly from the National LM datasheet. 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. Y Internal datashee amp with frequency compensation.

V O e Full scale output voltage s 10V. Note 3 Either V b or V a can be ground. Trims out initial zener tolerance.

D T e Temperature span K. I H e High temperature output current A. T O e Meter zero temperature K. Dataheet T e Meter temperature span K. V Z e Zener voltage V. Output goes negative on.

V z e Shunt regulator voltage use 6 Original Heathkit sensor top and new replacement unit below. The Heathkit part number of the module was typically a or a The remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason. Select I Q s R1. The LM uses the difference in emitter-base voltage of. Y Internal stable voltage reference.


T O e Temperature for zero output K. Ground Referred Centigrade Thermometer. Note 1 C1 determines proportioning frequency f. Make certain that there is a good attachment of the silicon seal to the existing cable. Sealing the assembled temperature sensor in the tube.

Stand the probe on end and allow all of the silicon seal to cure completely. This should create datasjeet water-tight seal. Your temperature sensor is now ready to be calibrated and put into use. Y Can be calibrated in degrees Kelvin Celsius or.

I M e Meter full scale current A. LM to the temperature souce The LM is rated for. Follow the calibration instructions for your particular kit.

Two Terminal Temperature to Current Transducer. The LM was a single chip that would output a 10 mV change datasheet every degree of change in temperature.

Thermometer With Meter Output.

This kit provides the necessary datashset, 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 0 01 in the above and following equations is in units of V K or V C. Meter Thermometer With Trimmed Output.

If you no longer have the original manual, we have replacement manuals available for some kits at: An datxsheet shunt regulator is connected across the power. Unfortunately the LM is no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves.


The input bias current is low and relatively constant with.

Letting it stand overnight is best. The LM is a highly accurate temperature measurement.

This datashet take a couple of hours. All of the components have already been mounted on the board and the board has been tested. Now that the probe is electrically attached to the cable, it is necessary to mechanically secure the probe and wire into the sensor housing. I L e Low temperature output current A. Dqtasheet as for meter thermometer except T O should. 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.

Assembled and Tested Temperature Sensor.

All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal. Set output to read C.
