Conax-111 Sensrs/Assm Art 2/11/00 4:52 PM Page 2 RTD & THERMOCOUPLE ASSEMBLIES FOR INDUSTRY COMMON MOUNTING STYLES: Direct-mount - Male threads screw directly into the vessel, securing the sensor assembly. Multiple mounting configurations are shown. PG Series Packing Glands (PG) - Single bore compression sealing glands of stainless steel construction include a "soft industrial sealant" that allows adjustable immersion, securing of probe, and environment sealing. Midlock Fitting (MK) - This all stainless steel assembly is used for gas or liquid sealing and may be opened and resealed at a fixed immersion depth. W-Fitting (W) - A stainless steel fitting is brazed or welded to the probe for a rugged leak-tight mounting. Nipple-Union-Nipple Configuration (NUN) - This configuration allows the terminal head to be positioned for easy assembly and alignment with conduit. Optional spring-loaded nipple is supplied for use with thermowell assemblies. Thermowells (T/W) are available in varying configurations in stainless steel, alumina oxide (Al2O3) or brass for additional protection of your sensor assembly. A weld pad (F) can be provided to allow easy welding of a sensor hot junction directly to a pipe or other surface. Adjustable fittings may be installed onto any terminal/probe assembly, allowing probe adjustment and environmental sealing. TERMINATION HEADS: 1. T7 Terminal Box: The weatherproof gasketed aluminum T7 terminal box can accommodate up to 40 terminals and is ideal for multiple probe or extra long thermocouple assemblies. 2. T11 Screw Cover Head: The T11 termination provides a screw cover with chain leash and a 6-post terminal block. The T11 is available in cast aluminum (AL) or plastic (PL). An optional spring loaded assembly allows complete disassembly and removal of the sensor probe without dismantling the terminal head from the conduit or vessel. 3. T8E Explosion-Proof Head (CSA/NRTL/C & UL): T8E assemblies can be supplied to meet CSA/NRTL/C standards with UL terminations for use in hazardous locations. 4. T8E Explosion-Proof Head (NEMA 7): The T8E explosion-proof head features a gray iron body with an aluminum screw cover. It accommodates up to 8 leads. This termination meets NEMA 7 requirements. 5. T5 Terminal Head (NEMA 4): The T5 ("O"-ring sealed) is a highly versatile NEMA 4-rated head featuring 6 terminal posts. It is available in aluminum, cast iron and stainless steel. 6. T8 Screw Cover Head: The T8 is our standard, weatherproof cast iron, gasketsealed screw cover head with black epoxycoated (E-COAT) exterior for corrosion prevention. This head accepts up to 8 leads. 6 PLUG AND JACK ASSEMBLIES 7. T12 Camlock Head: The T12 features an easyto-open globe design with camlock. A simple flick of the lock provides easy access to this weatherproof aluminum head. The T12 accepts up to 4 leads. 8. P4 Miniature Plastic Head: Miniature, weatherproof terminal head for corrosive environment applications provides 4 terminals. 9. Roll Temp Assemblies: Roll Temp assemblies are ideal for sensing surface temperature on drums, rollers or other moving surfaces. These are designed to detect temperature variations in continuous process applications for relative temperature measurement. These include high temperature assemblies (HTRT), sliding contact assemblies (RT) and high-speed assemblies (HSRT). T/W SENSOR ACCESSORIES SIGNAL CONDITIONERS: Conax Buffalo offers multiple types of industrial temperature transmitters, including: 2 6 F 5 The PJ Series of polarized plug and jack assemblies are made of molded, glass-filled thermoset compounds with contacts made of thermocouple alloys. They are available as male only (PJ) female only (PF), male/female assemblies (PJF) and male/female assemblies with cable clamp (PJFC). High temperature assemblies are available for applications above 400°F. 1. Dual Plug & Jack assemblies offer four-wire configuration. 2. 3-Prong versions are available for RTD assemblies. PJF 1. The Model HPTI is a small, 4-20 mA output, isolated 2-wire transmitter for RTD or thermocouple sensors. This will fit into any T5, T11 or T12 series terminal head. 2. The Model PTH-400 is a small, PC-programmable, 2-wire transmitter with a state-of-the-art microprocessor-based design. This is fully configurable with simple, user-friendly software. 3. The Model HST HART® Smart isolated 2-wire transmitter features universal input capability to accept most of today's process parameters, including thermocouples, RTDs, DCmV, potentiometers, resistance sensors, DCmA, DCA, AC amps, frequency and pulse. It is fully software driven and programmable. 3 4. The Model DRT2-RTD and DRT4-RTD are compact, DIN rail-mounted transmitters for 2-, 3- and 4-wire RTD sensors. The output is linear with respect to the sensor's temperature. The 4-wire input circuitry provides near-perfect compensation for the effect of long leadwire resistance. These units are powered by a standard industrial-loop power supply and provide a 4-20mA output on a 2-wire transmitter system (DRT2-RTD) or any standard current or voltage output on a 4-wire system (DRT4-RTD). 5. Conax Buffalo Con-O-Clad ®: Conax Buffalo produces in-house our exclusive mineral insulated (MgO) Con-O-Clad bulk material for single and multiple pair wires. This is available in all ISA base metal calibrations for thermocouples in sizes from 0.040 to 0.375 inch diameters. Other non-standard material combinations can be furnished for special requirements. 6. Thermocouple Extension Wire: Conax supplies bulk wire in a variety of insulation materials and ISA calibrations for use in various environments, including indoor, outdoor, corrosive, non-corrosive and electrical noise areas. 7. Conax Pressure and Vacuum Sealing Assemblies: Conax manufactures a complete line of pressure/vacuum compression sealing glands for wires and probes. In addition to our wide range of standard products, virtually unlimited customized designs are available. All designs feature Conax-developed "soft sealant" technology that provides unequalled adaptability to meet the application needs of any industry. T/W 3 Miniature Plug & Jack assemblies are ideal for laboratory use. PJFC 5 PG HTRT 9 1 PJ ADDITIONAL TERMINATION STYLES 7 HSRT 9 RT MK 9 1. Pipe clamps: Stainless steel pipe Clamp assemblies are available for use with all Conax Buffalo probes for accurate reading of outside pipe temperatures. They can be used with any terminal head or with wire alone. 2. Type B Terminations: Compact, lightweight Type B heads make terminating probes easy and convenient. Available in 2-, 3- and 4-wire post configurations, these corrosion-resistant heads offer easy and convenient hookup of customer's extension wire. An "O" ring industrial seal prevents moisture intrusion. 8 1 NUN 3. Type C Terminations: C Series terminations provide a convenient, compact method to terminate one or more sensors within a single probe. Screw posts securely fasten lead wires in position. Metal parts are stainless steel, with black anodized aluminum covers. 4. Type D Terminations: The Type D disctype terminations feature a stainless steel base brazed to the sensor sheath. The terminal block uses an exclusive Conax Buffalo design with up to 6 barrier-type terminals on a ceramic block. 5. Basic Sensor: Conax Buffalo supplies the most basic sensor configuration, consisting of thermocouple wire surrounded with hard-fired alumina oxide (Al2O3) insulators. A one-inch lead termination is provided. 5 7 T SERIES TERMINATION STYLES 2 Conax Buffalo offers a number of sensor termination styles. The T1 basic configuration features a standard 1-inch bare wire lead, with ISA-designated color-coded Teflon®-sleeves. The probe end is impregnated with silicone compound to prevent liquid or gas penetration. The T2 3 configuration features a silicone-impregnated glass braid insulation combination swaged approximately 3/4-inch into the sheath. The T3 is epoxy-filled, with an exclusive Conax Buffalo strain harness design providing a practically unbreakable connection between the lead wire and probe lead. The T4 adds a stainless steel overbraid to the T3 configuration. This protects lead wires and offers maximum flexibility and resistance to abrasion.
