1. GENERAL INFORMATION This manual covers all AquaMetrix P60, P65, R60 and R65 Series differential measurement pH and ORP probes. All mounting configurations are described. Both those probes with encapsulated preamplifiers and those with encapsulated two-wire transmitters are covered. If your probe has five wires it has an encapsulated preamplifier (P60 and R60). If your probe has two wires, or in the case of an ORP probe four wires, it has an encapsulated two-wire transmitter (P65 and R65).
2. SPECIFICATIONS MEASURING RANGES pH: 0 to 14.00 pH ORP: R60: +1999 mV PRESSURE LIMIT 100 psig @ 65°C 40 psig @ 95°C R65: 0-1000 mV / +500 mV field selectable TEMPERATURE LIMITS FLOW RATE 10 ft./sec max.
3. INSTALLATION 3.1. General Instructions Specific instructions for each type of probe are given in the following pages. Common to all probes are the following instructions: a) If the distance between the probe and the instrument is such that a direct connection is not possible, the probe cable should be routed to a junction box with a terminal strip (AquaMetrix Part No. JB1). The box should be well sealed and away from corrosion danger.
Figure 1 - Wiring a P/R 60 to a Shark controller 3.3. Connecting the P/R 60 to a Shark TX/P a) Always power down the transmitter BEFORE connecting the probe cable. b) Make sure the transmitter is disconnected from the power source before wiring the probe to the terminal strip on the back side of the transmitter. c) Check the wiring. Use the diagrams below to insure that you’ve made the correct connections.
Figure 2 - Wiring a P/R 60 probe to a Shark TX/P transmitter 3.4. ORP 4-20 mA Probes, R65 a) ORP 4-20 mA probes have four wires; black, red, green and white. The red wire is to be connected to the +24 Vdc terminal and the back wire to the 24 Vdc common terminal via the load in the loop. b) For an instrument with a range of 0 to 1000 mV the green and white wires are to be shorted. c) For an instrument with a range of –500 to 500 mV the green and white wires are to be isolated from each other. 3.5.
to the process. A cable strain relief fitting should be used on the upper end of the pipe. In the kits a wire bracket is provided to aid in supporting the assembly. NOTE: An optional protective shroud, Part No. PROTECTOR-3 should be used on the electrode end of the probe to protect the electrodes from accidental contact with the tank bottom, sides or objects in the process. 3.6.
3.9. Sanitary Probe P60S, P65S, R60S, R65S a) The P60S is designed with a stainless steel flange to mate with a Tri-Clover ferrule TL14AM7-2-1/2. 3.10. Insertion mounting Series 4 Differential Probes a) Apply pipe sealant to the electrode end of the probe and screw it into the any standard 1-1/2” Male NPT. 3.11.
4.2. Replacement of Salt Bridge for Series 4, 6, 7 & S Differential Probes a) If the system cannot be calibrated after cleaning the probe, it may be necessary to replace the standard cell solution. A kit is available from Water Analytics for this purpose (Part No. C35-17K). Proceed as follows: Refer to DWG N106-60. b) Hold the probe vertically with the sensor face up. Insert long nose pliers in the blind holes in the salt bridge and turn counter-clockwise taking care not to damage the glass electrode.
5. TROUBLESHOOTING AND SERVICE 5.1. Checking 5-wire Differential Probes P60 and R60 The probe can be checked by a few simple measurements. Two pH buffer solutions, 7 pH and either 4 pH or 10 pH, and a multimeter are required. For ORP probes two calibration solutions, 200 and 600 mV, are required. Millivolt solutions may be ±20% of nominal value. Actual value is noted on the bottle. 5.1.1. P60C pH probes a) Clean the probe as described in Section 4.1.
5.2. Checking Probes P65 and R65 (4-20 mA output) a) The operation of the 2-wire, 4-20 mA, probe can be checked by a few simple measurements. Two pH buffer solutions, 7 pH and either 4 pH or 10 pH, and a dc milliammeter are required. 5.2.1. P65C pH Probe a) Disconnect the red wire at the instrument or power supply and connect it to the milliammeter (-) black. b) Connect the milliammeter (+) red to the instrument or power supply red wire output terminal. c) Rinse the probe and place it in 7 pH buffer.
5.3. Customer Service If a problem has not been resolved with the above procedures, a telephone consultation with your AquaMetrix representative, or directly with Water Analytics will provide the answer. Water Analytics 100 School Street Andover, MA 01810 978-749-9949 info@WaterAnalytics.net 5.4.
