Thermocouple probes with connection heads feature cast aluminum NEMA 4 screw covers with captive gasket and stainless steel chain. The 1/4" diameter probes are available with temperature sensing ranges of 32 to 1,330° (Type J) or 32 to 1,700° (Type K). Welded-style probes, in 6", 12" and 18" lengths, are bendable to adapt to installation requirements; spring-loaded probes are available in 4", 6" or 12" lengths. Prices start at $42.00.
Thermocouple welded and spring-loaded probes with 1/2" x 1/2" hex nipples allow easy replacement of existing probes and easy connection to wiring junction boxes. Available in 6", 12" or 18" lengths, the 1/4" diameter welded style is bendable to adapt to installation requirements, while the spring-loaded style provides positive tip contact in thermowells. Prices start at $33.75.
Available thermocouple probes with pre-attached plugs feature 1/8" or 1/4" diameter sheaths in 6" 12" or 18" lengths; thermocouple probes with lead wire transition come with a six-foot heavy-duty lead wire. Temperature sensing ranges are 32 to 970° or 32 to 1330° (Type J) and 32 to 1700° (Type K). Prices start at $17.25.
Type J or K thermocouple adjustable immersion sensors, ideal for plastics processing applications, feature a 32 to 900° temperature range and 4, 6, or 10-foot lead wires; the spring and armor adjustable styles allow for variable immersion depths. Adjustable immersion sensors start at $16.00.
Bolt-on ring sensors are ideal for nozzles, extruder barrels, die heads, molds and other surface-mount sensing applications. Thermocouple bolt-on ring sensors with a 32 to 900° temperature sensing range start at $15.25; RTD bolt-on ring sensors with a -58 to 572° temperature sensing range are available for $54.00.
RTD probes feature 1/4" diameter stainless steel sheaths with 100 ohm platinum three-wire elements. With a temperature sensing range of -58 to 572°, the probes are available in 6", 12" or 18" lengths. Models available include welded and spring-loaded probes with cast aluminum NEMA 4 connection head and captive gasket, 3/4" NPT conduit opening and stainless steel cover chain; probes with 1/2" x 1/2" hex nipples are available in welded and spring-loaded styles, allowing for easy replacement of existing probes and connection to wiring junction boxes. Also available are probes with pre-attached three-pin plugs for quick and easy wiring connection, as well as probes with lead wire transition or M12 connections. RTD probes start at $29.00. RTD thermowells are available for use with certain probes, starting at $23.50.
ProSense RTD sanitary Clean-in-place probes are designed to meet the stringent requirements of HTST pasteurization systems. These 4-inch probes are available in the standard 1/4" diameter or with a 3/16" diameter reduced tip for greater durability in high-viscosity applications. The stainless steel probes have a -58 to 400° temperature sensing range. Clean-in-place probes start at $89.00.
Two-conductor thermocouple extension wire for types J and K, in standard ASTM/ANSI colors, are available in convenient 50-foot and 100-foot lengths starting at $15.00. Also available is RTD extension wire which offers superior performance compared to "off-the-shelf" cable. Starting at $21.00, the three-conductor wire is available in 50-foot and 100-foot lengths.
