Element Specifications
Back to Top
Element Material | |||
Your choices are... | |||
Platinum | Platinum provides measurement integrity and is the most commonly used metal for RTDs. | ||
Nickel/Nickel Alloys | Nickel and nickel alloys are commonly used and economical, but not as accurate as platinum. | ||
Copper | Copper is used occasionally as an RTD element. Its low resistivity, however, requires the use of a device that is longer than a platinum element. Copper provides good linearity and is economical. Typically, its upper temperature range is less than 150° Celsius. | ||
Other | Other unlisted element materials. | ||

Sensed Temperature Range
Back to Top
Sensed Temperature | Sensed temperature is the temperature range for which the device is rated for sensing. | ||
Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
Probe Configuration

Probe Configuration | |||
Your choices are... | |||
Straight Probe | Straight probes measure stationary surface temperatures and can be used in wells. | ||
Penetration (Needle) Probe | Penetration probes or needle probes are used to measure internal temperatures. | ||
Flexible Probe | Flexible probes can be manipulated for various temperature measurements. | ||
Drop Probe | Drop probes are designed for well or underwater temperature measurements. | ||
Curved Probe | Curved probes are used to measure temperatures on pipes or other curved surfaces. | ||
Roller or Moving Probe | Roller probes or moving probes measure temperatures on moving surfaces. | ||
Air Probe | Air probes are designed for air-flow temperature measurements. | ||
Angled Probe | Angled probes are used for temperature measurement applications inside pipes and angled spaces. | ||
Surface | Surface probes attach to skin or a flat surface. They are also known as banjo, patch, or bolt-on probes. | ||
Clamp or Strap Sensor | Clamp probes or strap sensor probes clamp or wrap around the surface to be monitored. | ||
Flat/Ribbon | Flat probes or ribbon probes are temperature sensors with a flexible membrane. | ||
Other | Other unlisted or specialized probe configurations. | ||

Diameter or Width Range | Depending on the probe configuration, this dimension is either the diameter or width of the probe, or the diameter of the object being monitored. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
Sensitive Length | Depending on the probe configuration, this dimension is either the height or length of the temperature-sensitive part of the probe. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
Process Connection | There are many ways to connect a probe to a monitored process. This section describes standard connection methods, but is not an exhaustive list. | ||
Your choices are... | |||
None or Hand held | Probes do not include a process connection. Typically, these devices are hand held probes. | ||
Bayonet | Bayonet fittings consist of a socket with J-shaped slots on opposite sides. A bayonet base or coupling is inserted against a spring and rotated until its pins are firmly seated. | ||
Threaded Fitting | Threaded fittings are continuous helical ribs, like on a pipe. Styles include national pipe thread (NPT), imperial or English, and metric. | ||
Compression | Compression fittings have a tapered sleeve and are used mainly with tube fittings. | ||
