  • Page 5: Introduction

    Installation / Operation Manual Introduction The 4728 S & W Monitor used in conjunction with a Model 4528 Detector Card and Model CX-645 Probe, provides continuous on-line monitoring of percent water in crude oil. The monitoring system measures changes in the product stream capacitance. The di- electric constant (Dk) (a key factor in capacitance measurement) of the product stream changes dramatically as water content varies.
  • Page 6: Percent Water Set Point

    Model 4728. The 20 mA point is factory preset. The Model 4728 utilizes a loop switch to determine whether the 4-20 mA loop will be self powered or powered by a remote supply. In the internal mode the unit will drive 4-20 mA through a maximum loop resistance of 600 ohms.
  • Page 7 Failure to have the switch in the proper position may cause component failure and void the unitʼs warranty. The function and operation of all other controls on the 4728 are as described in the manual. Issue/Rev. 0.0 (5/19) ║ MNIN003 • Page 7...

    Installation / Operation Manual Model 4528 Detector – Types A, B, and C The Model 4528 Detector mounts in the explosion proof conduit on the capacitance probe. It converts water changes in the oil flowing through the probe to an output volt- age that varies with the water.

    Warning: Loop Switch MUST be up in external position BEFORE connecting external power on 4728 with bottom terminal strip. Loop Switch MUST be up before connecting external power on CSA Approved Model 4728 with the two sides and bottom terminal strips.
  • Page 11 Installation / Operation Manual The probe is constructed of two concentric tubes. Wetted and internal surfaces are coated with a fused epoxy powder. The inner tube is insulated from the outer tube by PTFE (polytetrafluoroethylene) spacers and is electrically connected to a terminal within the sensor housing.

    Turn on power/system to cause oil to flow through probe. Allow flow to stabilize. Take grindout of water in oil. For calibration purposes the oil should preferably have less than 1% water in it. Apply power to Model 4728 indicator unit. Ignore lights until calibration is complete. A. 4528 Detector 1.

Calibration 4528-X A With 4-20 mA Module Mounted “Piggy Back” on Detector Card 1. Remove Detector aluminum face plate by removing the three 6-32 mounting screws and the bottom screw on P.C.
  • Page 16 2. The 4-20 mA loop is internally powered from the 4528-A. DO NOT USE an external loop power source. The 4528-5A Detector Card is designed to supply a 4-20 mA signal direct to an external readout device. It is not designed to be used with a Model 4728 Readout Unit. 3. Maximum Loop Resistance is 250 ohms.

    Installation / Operation Manual Detector Information – Type B and C Type “C” Detector with Fail-safe Switch - This switch allows the output from the Detector Chassis to be tailored to the requirements of the customer. The Fail-safe Switch is located on the upper right side of the printed circuit board under the cover plate.
