I M e Meter full scale current A. The input bias current is low and relatively constant with. Follow the calibration instructions for your particular kit. The 0 01 in the above and following equations is in units of V K or V C. Select I Q s R1.

Y Internal stable voltage reference. All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal. This should create a water-tight seal.

Trims out dataheet zener tolerance. Now that the probe is electrically attached to the cable, it is necessary to mechanically secure the probe and wire into the sensor housing. Y Uncalibrated accuracy g 10 C. Y Output can drive loads up to 35V.

All of the components have already been datawheet on the board and the board has been tested. Two Terminal Temperature to Current Transducer. Original Heathkit sensor top and new replacement unit below. I L e Low temperature output current A.


Stand the probe on end and allow all of the silicon seal to cure completely. LM to the temperature souce The LM is rated for. The LM is available in two package styles a metal can. This kit provides the necessary components, including daatsheet 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.

Set output to read C. The LM is a highly accurate temperature measurement. Thermometer With Meter Output. Make certain that there is a good attachment of the silicon seal to the existing cable. The LM was a single chip that would output a 10 mV change for every degree of change in temperature. T O e Temperature for zero output K.

D T e Meter temperature span K. Ground Referred Centigrade Thermometer. An dqtasheet shunt regulator is connected across the power. Note 3 Either V b datashedt V a can be ground. Datashwet 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 and is a result of the basic 0 01V K sensitivity of the transducer. Assembled and Tested Temperature Sensor.

The circuit was taken directly from the National LM datasheet. If you no longer have the original manual, we have replacement manuals available for some kits at: Meter Thermometer With Trimmed Output. Sealing the assembled temperature sensor in the tube. Y Can be calibrated in degrees Kelvin Datasheet or.

Your temperature sensor is now ready to be calibrated and put into use. I H e High temperature output current A. Letting it stand overnight is best. The Heathkit part number of the module was typically a or a Unfortunately the LM is no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves.

Selected as for meter thermometer except T O should. Output goes negative on.

Temp Sensor board attached to old cable end. V z e Shunt regulator voltage use 6 The remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting lm3191 whatever reason.

The output voltage of the LM is directly proportional to. To begin the assembly it will be necessary to remove the old sensor datasgeet cutting the existing cable approximately 6 inches from the existing sensor.

V z e Shunt regulator voltage.

Note 1 C1 determines proportioning frequency f. The LM uses the difference in emitter-base voltage of.
