Temperature Probes, RTD Specifications

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.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Additional Probe Specifications


	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.
	Braze, Weld or Solder		Braze, weld, or solder fittings are designed to be brazed, welded, or soldered into place.
	Other		Other unlisted or specialized process connections.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Sensor Termination Type		There are various methods for probe terminations. Sensor termination type is an important parameter when trying to match a probe with an instrument, transmitter or other signal conditioning equipment.
	Your choices are...
	Bare or Insulated Lead Wires		Devices use bare or insulated lead wires.
	Metal Braided Leads		Devices use metal braided leads.
	Armor Leads		Devices use armor leads.
	Flexible Conduit Leads		Devices use flexible conduit leads.
	Terminal Block		Devices use terminal blocks.
	Conduit Connector		Devices use conduit connectors.
	Screw Tabs or Lugs		Devices use screw tabs or lugs.
	Integral Connection Head (Thermohead)		Devices use integral connection heads (thermoheads).
	Plug or Quick Connect		Devices use plugs or quick-connects.
	Other		Other unlisted or specialized sensor termination type.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features and Options


	Probe Features
	Your choices are...
	Available as an Assembly		Devices are complete or partial assemblies with a thermowell, fittings, and transmitter or thermohead.
	Cuttable		Probes can be cut to specific lengths.
	Spring Loaded		Spring loading ensures proper contact with the tip of the thermowell or the surface to monitor.
	Tip Sensitive		With tip-sensitive probes, only the tip of the probe is temperature-sensitive.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
