Discussion Overview

The discussion revolves around the implications of an unspecified operating temperature in a device's data sheet. Participants explore whether the absence of this information indicates that temperature is not a concern for operation or if it suggests limitations based on manufacturer testing.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants suggest that the lack of an operating temperature specification does not imply that the device can operate at any temperature, including extreme lows like -90 degrees Celsius.
  • One participant proposes that the absence of temperature information likely indicates that the manufacturer has only tested the device at a standard temperature, such as 25 degrees Celsius.
  • Another participant emphasizes the importance of consulting the manufacturer directly for reliable information regarding operating conditions.
  • A participant mentions the presence of a metal to glass seal in the device, implying that the manufacturer should typically provide limits for operation and storage in the data sheet.

Areas of Agreement / Disagreement

Participants express differing views on the implications of not having an operating temperature specified. There is no consensus on whether this absence indicates flexibility in temperature operation or a lack of testing by the manufacturer.

Contextual Notes

Participants note potential limitations in the data sheet, including missing assumptions about temperature ranges and the manufacturer's testing protocols.

if operating temperature in a data sheet is not given??

if the operating temperature is not mentioned in the data sheet of a device, does it mean that the temperature is a non-issue and that it can operate at any temperature?even -90celsius??
 
Engineering news on Phys.org


No.
Probably means it can only operate at 25 degree C.

Can you post a link to the datasheet?
 


better yet...i've attached the data sheet...

It probably means that the manufacture has not tested it at temperature.
Manufacture has a free telephone number that you can call. Call the manufacture and ask him. The answer you get will be much more reliable than anything that you get on an engineering forum.
 


there's a metal to glass seal someplace in that device. The manufacturer's ceramic engineer knows its limits and I'm surprised it's not in the datasheet. Usually the limit for operation and storage are both given.

I bet Perkin-Elmer will appreciate your pointing it out.
