LM3911 Datasheet PDF

Sealing the assembled temperature sensor in the tube. All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal. 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. Y Internal stable voltage reference. I M e Meter full scale current A.

Ground Referred Centigrade Thermometer. T O e Temperature for zero pm3911 K. V z e Shunt regulator voltage. The LM is available in two package styles a metal can. T O e Meter zero temperature K. This will take a couple of hours. The Heathkit part dataheet of the module was typically a or a V 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. All of the components have already been mounted on the board and the board has been tested.

Thermometer With Meter Output. D T e Meter temperature span K.

The LM is a highly datadheet temperature measurement. The LM uses the difference in emitter-base voltage of. V Z e Zener voltage V. I L e Low temperature output current A. Now that the probe is electrically attached to the cable, it is necessary to mechanically secure the probe and wire into the sensor housing.

Make certain that there is a good attachment of the silicon seal to the existing cable. Y Uncalibrated dqtasheet g 10 C.

This should create a water-tight seal. Set output to read C. Output datasheet negative on. Note 3 Either V b or V a can be ground. The output voltage of the LM is directly proportional to. Y Internal op amp with frequency compensation.

Temp Sensor board attached to old cable end. Follow the calibration instructions for your particular kit. Unfortunately the LM is no longer available and even small quantities have disappeared from surplus dealer’s and distributor’s shelves. D T e Temperature span K. Original Heathkit sensor top and new replacement unit below. LM to the temperature souce The LM is rated for. 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.

Y Output can drive loads up to 35V. Assembled and Tested Temperature Sensor. Note 1 C1 determines proportioning frequency f.

Meter Thermometer With Trimmed Output. An active shunt regulator is connected across the power. The remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason.

The circuit was taken directly from the National LM datasheet. Letting it stand overnight is best. The LM was a single chip that would output a 10 mV change for every degree of change in temperature. Stand the probe on end and allow all of the silicon seal to cure completely.

Your temperature sensor is now ready to be calibrated and put into use. V z e Shunt regulator voltage use 6 I H e High dattasheet output current A.
