La sonde contient un élément de platine de 100 ohms à couche mince de précision Classe "A" ou "B" DIN standard. D'autres résistances et classes disponibles
Scellé contre l'humidité et la corrosion
Câble isolé en PFA
Gamme de température : -60 à 260 °C
Configuration standard à 4 fils
Embout de la sonde à RTD scellé hermétiquement
Temps de réponse : 3,75 secondes max dans l'eau circulant à 3 pieds par seconde (63%)
Les sondes flexibles de température à RTD's de la série HSRTD sont scellées hermétiquement à l'embout afin de fournir une protection continue de la jonction de la mesure de température. Le câble flexible en PFA de la sonde scelle hermétiquement et isole électriquement le petit senseur à RTD ce qui lui permet de pouvoir être utilisé dans une grande variété d'applications. Le procédé unique de fabrication d'OMEGA ne produit pas d'augmentation du diamètre ni de changement de la forme de la pointe de la sonde, permettant son installation dans les endroits où l'espace est limité. Fourni en standard avec terminaison fils dénudé. D'autres connecteurs et d'autres longueurs de câble de raccordement sont également disponibles.
Pour une sonde à thermocouple hermétiquement scellée, voir le modèle HSTC

Resistant to magnetic flux changeI 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 ProbeThe RTD probe arrived quickly and is as described. The materials seem high quality and it performs as expected.

Durable and easy to useI 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.
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.
Asked by: CL Lee
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?
Asked by: benjfitz
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?
Asked by: ned_pcs
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?
Asked by: Bob3i33
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.
Asked by: Winnie
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.
