It is important that all instructions are read carefully before insertion and removal. Detailed instructions are included in the General Instructions section of this manual. Conventions Used in this Manual Certain conventions are used in this manual to convey specific types of information. General technical material, support data, and safety information are presented in narrative form. The following styles are used for notes, cautions, and warnings. Notes Notes contain information that augments or clarifies an operating step. Notes do not normally contain actions. They follow the procedural steps to which they refer. Cautions Cautions alert the technician to special conditions that could injure personnel, damage equipment, or reduce a component’s mechanical integrity. Cautions are also used to alert the technician to unsafe practices or the need for special protective equipment or specific materials. In this manual, a caution box indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. Warnings Warnings identify potentially dangerous situations or serious hazards. In this manual, a warning indicates an imminently hazardous situation which, if not avoided, could result in serious injury or death. Safety Messages Follow all standard industry procedures for servicing electrical equipment when working with or around high voltage. Always shut off the power supply before touching any components.

The Retractable Probe Assembly permits the probe or transducer to be installed in or removed from the vessel or pipe while the process is in operation. After initial installation, it is not necessary to drain or depressurize the tank or shut down the operation to install the instrument. The Retractable Probe Assembly is made from 316 stainless steel with optional carbon steel or stainless steel flanges and ball valves. Various designs permit operation up to ANSI Class 300 pound service. 1.1 Features • Permits insertion or removal of the probe or transducer without shutting down the process or draining the tank. • Suitable for use with stainless steel Thermatel probes, Echotel probes, and Kotron probes with inactive sheath. Probes must have a 3⁄4" process connection. • NPT or flange mounted • Optional ball valve • Teflon® compression rings • Stainless steel gland assembly with choice of carbon steel or stainless steel process connections. • Prevents unintentional removal of instrument. • Standard pressure to 50 psig (80 psi for TA1/TA2 probes). High pressure design optional to class 300 pound service. • Temperatures to +400° F (+204° C) 1.2 Pressure-Temperature Chart HIGH PRESSURE DESIGN 1000 900 800 Pressure (psig) 700 600 500 400 300 200 100 0 0 100 Temperature ° F 200 300 400 500 150 lb. flange Threaded or 300 lb. flange 41-103 Hot Tap Retractable Probe Assembly 1 2.0 2.1 General Instructions Probe Insertion 1. Ensure that the ball valve is closed. 2. Loosen the seal nut of the Retractable Probe Assembly and insert the probe. 3. Attach the safety cable to the retaining ring (low pressure) or connect the probe to the 3⁄4" NPT connection on the retaining bar (high pressure). 4. Carefully slide the probe past the Teflon sealing rings ensuring that the probe tip does not hit the closed ball valve. Optionally, the Retractable Probe Assembly may be disassembled to slide the seal nut and Teflon v-rings over the probe before inserting into the gland nut. 5. Slightly tighten the seal nut to permit movement of the probe past the Teflon v-rings, but also to avoid leakage. 6. Open the isolation ball valve and insert the probe to the desired location in the vessel. For Echotel and Thermatel sensors, properly align the probe/transducer in the vessel. 7. Tighten the seal nut. 2.2 Probe Removal 1. Slightly loosen the seal nut to permit movement of the probe, but also to avoid leakage. 2. Withdraw the probe from the vessel to the length permitted by the safety chain or adjustment rods. 3. Close the isolation valve. 4. Remove the probe from the safety cable (low pressure) or disconnect the probe from the retaining bar (high pressure). 2 41-103 Hot Tap Retractable Probe Assembly 3.0 3.1 Reference Information Dimensional Specifications 3/4" 3/4" NPT Retaining bar NPT Retaining bar Adjustment rods Adjustment nuts Adjustment rods Adjustment nuts Seal nut Seal nut S Dimension (minimum) Threaded connection 4.00 Flanged connection 5.00 T Ball valve Ball valve V X X Customer connection Vessel wall H V T Y Ball Valve Dimensions* Size V 11⁄2" NPT 4.4 11⁄2" 150# flange 6.5 11⁄2" 300# flange 7.5 *Dimension of ball valve if supplied by Magnetrol.

They will be rebuilt or replaced promptly. Controls returned under our service policy must be returned by Prepaid transportation. Magnetrol will repair or replace the control at no cost to the purchaser (or owner) other than transportation if: 1. Returned within the warranty period; and 2. The factory inspection finds the cause of the claim to be covered under the warranty. If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be charges for labor and the parts required to rebuild or replace the equipment. In some cases it may be expedient to ship replacement parts; or, in extreme cases a complete new control, to replace the original equipment before it is returned. If this is desired, notify the factory of both the model and serial numbers of the control to be replaced. In such cases, credit for the materials returned will be determined on the basis of the applicability of our warranty. No claims for misapplication, labor, direct or consequential damage will be allowed. Return Material Procedure So that we may efficiently process any materials that are returned, it is essential that a “Return Material Authorization” (RMA) number be obtained from the factory, prior to the material's return. This is available through Magnetrol’s local representative or by contacting the factory. Please supply the following information: 1. 2. 3. 4. 5. Company Name Description of Material Serial Number Reason for Return Application Any unit that was used in a process must be properly cleaned in accordance with OSHA standards, before it is returned to the factory. A Material Safety Data Sheet (MSDS) must accompany material that was used in any media. All shipments returned to the factory must be by prepaid transportation. All replacements will be shipped F.O.B. factory. 5300 Belmont Road • Downers Grove, Illinois 60515-4499 • 630-969-4000 • Fax 630-969-9489 • www.magnetrol.com 145 Jardin Drive, Units 1 & 2 • Concord, Ontario Canada L4K 1X7 • 905-738-9600 • Fax 905-738-1306 Heikensstraat 6 • B 9240 Zele, Belgium • 052 45.11.11 • Fax 052 45.09.93 Regent Business Ctr., Jubilee Rd. • Burgess Hill, Sussex RH15 9TL U.K. • 01444-871313 • Fax 01444-871317 5300 Belmont Road • Downers Grove, Illinois 60515-4499 • 630-969-4028 • Fax 630-969-9489 • www.sticontrols.com Copyright © 2007 Magnetrol International, Incorporated.
