Section 2: Installation

2.1Unpacking and Inspection

Inspect the outside of the carton for any damage. If damage is detected, contact the carrier immediately. Inspect the hardware. Make sure all the items in the packing list are present and in good condition. Notify the factory if any part is missing. If the sensor appears to be in satisfactory condition, proceed to Section 2.2, Mounting.

NOTE: Save the original packing cartons and materials as most carriers require proof of damage due to mishandling, etc. Also, if it is necessary to return the sensor to the factory, you must pack the sensor in the same manner as it was received. Refer to Section 6.0 for return instructions. If the sensor is to be stored, the vinyl boot should be filled with pH buffer solution and replaced on sensor tip until ready to use.

CAUTION

Buffer solution, in the vinyl boot, may cause skin or eye irritation.

WARNING

Glass electrode must be wetted at all times (in storage and in line) to maximize sensor life.

2.2Mounting

The sensor has been designed to be located in industrial process environments. Temperature and pressure limitations must not be exceeded at any time. A caution label regarding this matter is attached to the sensor. Please do not remove the label. See Figure 2-1.

CAUTION

Internal electrolyte fill solution may cause skin or eye irritation.

Mounting Guidelines:

1.Shake the sensor in a downward motion to remove any air bubbles that may be present inside the tip of the pH glass.

2.Do not install the sensor on the horizontal. The sensor must be 10° off the horizontal to ensure accuracy.

3.Do not install the sensor upside down.

4.Air bubbles may become trapped in the sensor end between the glass bulb and the sensor body. This problem is most commonly encountered in areas of low flow or during calibration. Shake the probe while immersed in solution to remove bubbles. This problem can be avoided by ordering the sensor with the slotted tip (option -41).

In most cases, the pH sensor can simply be installed as shipped and readings with an accuracy of

±0.6 pH may be obtained. To obtain greater accuracy or to verify proper operation, the sensor must be calibrated as a loop with its compatible analyzer or transmitter.
