Hi there,

Are both CX-1080-BC-HT-20L and CX-1080-SD-HT-20L sensors' performance same but in different packages?
Can I use "CX-1080-BC-HT-20L" DIRECTLY on my circuit board though it is a "bare chip"?
or I have to use "CX-1080-SD-HT-20L" which is in SD package on my board?

Thanks
Sheng

I can't answer your application question in terms of mounting on a circuit board. I'll let Jeff or Ogie answer that.

But yes, that is the same sensor, one without a package (BC) and one in an SD package.

This Sensor Selection Guide may help point you in the right direction. If not, one of the other guys here will.

Most customers I know use a bare chip when mounting to a circuit board, however, either sensor can be used.

I suggest you review the information on mounting the bare chip at www.lakeshore.com/docs/default-source/product-downloads/installation-instructions/f002-00-00.pdf?sfvrsn=ae9682e2_4 for more information.

Hi Jeff, Admin or others,

For CX-1080-BC-HT-20L vs CX-1080-SD-HT-20L: because these RTD sensors are type of resistor, so, I can inject current into it through either of its two pins, right? (in other words, its two pins are not polarized, right?)

Regards
Sheng
