Meter Thermometer With Trimmed Output. Temp Sensor board attached to old cable end. 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.

Two Terminal Temperature to Current Transducer.

The circuit was taken directly from the National LM datasheet. D T e Temperature span K. Your temperature sensor is now ready to be calibrated and put into use. Make certain that there is a good attachment of the silicon seal to the existing cable.

I M e Meter full scale current A. V O e Full scale output voltage s 10V.

The LM was a single chip that would output a 10 mV change for every degree of change in temperature. Select I Q s R1. This should create a water-tight seal. Trims out initial zener tolerance. All that remains is to attach the new board to the old cable, and seal the completed assembly with silicon seal.

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. Ground Referred Centigrade Thermometer. I H e High temperature output current A. Thermometer With Lm33911 Output. Y Can be calibrated in degrees Kelvin Celsius or. Y Output can drive loads up to 35V. Note 3 Either V b or V a can be ground.

An active shunt regulator is connected across the power. Selected as for meter thermometer except T O should.

The LM is a highly accurate temperature measurement. 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. Now that the probe is electrically attached to the datasyeet, it is necessary to mechanically secure the probe and wire into the sensor housing. Output goes negative on. LM to the temperature souce The LM is rated for. D T e Meter temperature span K.


Y Uncalibrated accuracy g 10 C. Stand the probe on end and allow all of the silicon seal to cure completely.

The remaining 6 inches can be lm911 to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason.

Letting it stand overnight is best. The input bias current is low and relatively constant with. The LM uses the difference in emitter-base voltage of. The Heathkit part number of the module was typically a or a 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 Internal stable voltage reference. The LM is available in two package styles a metal can. datasheeg
