Resistant to magnetic flux change
I have probably purchased 30 of these over the last 5 years. They perform much better than bimetallic thermocouples for reading temperature in magnetic induction applications. The durability is good, but not outstanding in harsh environments, especially in steam at temperatures greater than 120°C (thus the purchase of 30 over the last 5 years). Their response is faster than metal clad RTDs. The rapid response allows for more contained PID controll. It would be wonderful if Omega made a steam-tolerant packing gland for the RTD where the RTD tip was not in contact with a metal (as is the case in a thermowell).

RTD Probe
The RTD probe arrived quickly and is as described. The materials seem high quality and it performs as expected.

Durable and easy to use
I use these to measure the temperature on the backside of PV modules. The RTDs are easy to use and they are very durable. The pre-tinned wire leads make installation very easy.

Has anyone tried soldering this wire? I'm using 245 Sn63Pb37 solder and it's having terrible problems beading up at all temps. Any suggestions for improvement are appreciated.
Megan, in general beading up could be caused by lack of sufficient flux, or excessive oxidation or contamination. If your solder flows to the heated surface and is unable to bond due to surface being oxidized it will tend to form a ball/bead.
You could try cleaning the surface free to dirt/oil/oxidation. You could try using steel wool to scrape off the oxidation as long as it does it damage your process.
Make sure you are not overheating, since overheating can burn off the flux prematurely. High temperatures burns off the flux way too fast and prevents a good bond
You could also try a different brand of solder wire. For further questions feel free to email us at temp@dwyeromega.com

Could this RTD sensor measure at temperature for -80°C? I mean would it damage the sensor at -80°C? Let say if I gonna purchase & send to calibration lab for -80°C calibration and obtain the correction factor for this particular temperature to use this.
Hi CL Lee,
Thank you for the inquiry. The materials are verified to -60 C. I would suggest to test at your target temps for a period of time before investing in calibration for offsets.
Best regards

What is the self-heating coefficient of the 1000 ohm varieties? Also, does the excitation current of the CN32PT readouts change with the 100 ohm vs 1000 ohm RTDs?
Thank you for your inquiry benjfitz. The excitation current for 100 ohm or 1000 ohm RTD is 1 mA. The maximum the excitation current can be is 2 mA. Unfortunately, the self-heating coefficient is not available on our current documentation. Please send an email to temp@omega.com and one of our engineers will assist you in finding this information.

What is the self-heating coefficient of the HSRTD Pt100 sensors?
The nominal self heating specification for the probes RTD element would be 0.4K/mw at 0C.

I've ordered an Omega HSRTD-2-100-A-5M. Is this ok for using in a Class 1 Div 2 or Class 1 Div 1 location? If not, do you have a similar sensor (either 4-20mA or RTD) that is completely submersible in a corrosive environment like this one is?
Thank you for the inquiry. We do not offer any explosive area ratings on this series. We do not offer similar sensor with 4 to 20 mA output with explosive area rating.
Best regards,
OMEGA

I am looking to see if putting HSRTD-3-100-1/10-5M in coolant to measure its temp variation would be ok? Looking to make sure we don't contaminate or damage the sensor.
Thank you for your inquiry. The HSRTD is a hermetically sealed RTD sensor for immersion applications. It will work with coolant as long the temperature being measured is within the temperature range.
