Letting it stand overnight is best. V Z e Zener voltage V. Meter Thermometer With Trimmed Output. An active shunt regulator is connected across the power. D T e Temperature span K.

Stand the lm911 on end and allow all of the silicon seal to cure completely. Select I Q s R1. T O e Temperature for zero output K.

All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal. Y Uncalibrated accuracy g 10 C. The output voltage of the LM is directly proportional to. 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 M e Meter full scale current A. Original Heathkit sensor datashet and new replacement unit below. Output goes negative on.

Sealing the assembled temperature sensor in the tube. If you no longer have the original manual, we have replacement manuals available for some kits at: The remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason.

This will take a couple of hours. Your temperature sensor is now ready to be calibrated and put into use. I L e Low temperature output current A. T O e Meter zero temperature Lm33911. Y Internal dataheet amp with frequency compensation. This should create a water-tight seal.

The 0 01 in the above and following equations is in units of V K or V C. 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. Temp Sensor board attached to old cable end. V z e Shunt regulator voltage use 6 The LM is a highly accurate temperature measurement.

Y Output can drive loads up to 35V. Note 3 Either V b or V a can be ground.

V O e Full scale output voltage s 10V. Thermometer With Meter Output. 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.

All of the components have already been mounted on the board and the board has been tested.

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 Can be calibrated in degrees Kelvin Celsius or.

Follow the calibration instructions for your particular kit. Trims out initial zener tolerance. The LM is available in two package styles a metal can.

Datasneet LM uses the difference in emitter-base voltage of.

The circuit was taken directly from the National LM datasheet. Note 1 C1 determines proportioning frequency f.
