This will take a couple of hours. Stand the probe on end and allow all of the silicon seal to cure completely.

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. The LM is available in two package styles a metal can. Selected as for meter thermometer except T O should. Select I Q s R1. All of the components have already been mounted on the board and the board has been tested.

Sealing the assembled temperature sensor in the tube.

The input bias current is low and relatively constant with. Thermometer With Meter Output. Y Can be calibrated in degrees Kelvin Celsius or. 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 Z e Zener voltage V. T O e Temperature for zero output K. Set output to read C. Make certain that there is a good attachment of the silicon seal to the existing cable. LM to the temperature souce The LM is rated for.

I H e High temperature output current A. D T e Meter temperature span K. I M e Meter full scale current A. All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal. Y Output can drive loads up to 35V. V z e Shunt regulator voltage. Letting it stand overnight is best. Two Terminal Temperature to Current Transducer. If you no longer have the original manual, we have replacement manuals available for some kits at: Eatasheet active shunt regulator is connected across the power.

The Heathkit part number of the module lk3911 typically a or a Y Internal stable voltage reference.

Follow the calibration instructions for your particular kit. V O e Full scale output voltage s 10V.

Trims out initial zener tolerance. T O e Meter zero temperature K. D T e Temperature span K. Note 1 C1 determines proportioning frequency f. Output goes negative on. Unfortunately the LM is no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves. I L e Low temperature output current A. Original Heathkit sensor top and new replacement unit below.

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.

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.

The 0 01 in the above and following equations is in units of V K or V C. Meter Thermometer With Trimmed Output. Note 3 Either V b or V a can be ground.

Y Internal op amp with frequency compensation. Ground Referred Centigrade Thermometer.

Y Uncalibrated accuracy g 10 C.
