Electrical Resistance (ER) Probe Accessories PROBE ELEMENT SHIELDS ORDER INFORMATION All loop element Electrical Resistance (ER) and ER Temperature process probes (Models 2600**, 2610**, 3000**, and 4605) require shields to prevent damage to the exposed measuring element. Standard shields may be used in liquid flow rates up to approximately twenty feet per second*, depending on viscosity, particulate matter, element configuration and other factors. Cylindrical element ER and ER Temperature process probes (Models 2500, 3500, and 4500) may be used without shields in liquid flows up to approximately eight feet per second. However, standard shields are recommended at any velocity up to approximately 25 feet per second, to assure adequate protection of the element. All cylindrical element shields incorporate an element tip support to reduce the possibility of element failure from flow or fatigue. Retractable ER and ER Temperature probes (Models 3000** and 3500) use removable shields so that the stuffing box may be accessed for maintenance. Since these shields also act as the mechanical stop for the probe in the retracted position, they must be periodically inspected (and replaced if required) to maintain their mechanical integrity. HIGH VELOCITY shields reduce the fluid velocity past the element and allow the probe to be used in more severe environments. Loop element and cylindrical element probes may be used in liquid flows up to approximately 50 feet per second. COUPON HOLDING shields allow an electrically isolated blade type coupon to be mounted on the end of a loop or cylindrical element probe. This permits simultaneous coupon and ER data accumulation at a single probe location. The velocity limitation for coupon holding shields is the same as for standard shields. *Velocity limitations for probes in gases are approximately three times the velocities listed for liquids. **Also “G” versions.
