1 INTRODUCTION

1.1 General

The sensor and fitting program for inductive conductivity measurement (model ISC40) is designed to meet the most common installation requirements in terms of material compatibility, process connections and flow dynamics. The various installation possibilities are described and illustrated in this manual. The following categories of installation can be recognised:

1. Direct mounting of sensors in tank wall or customer supplied flanges

2. Cost effective installation of sensors using process adapters

3. Maintenance friendly installation of sensors using in-line subassemblies

4. Installation in flow chambers for measurements in sample streams or bypass loops

5. Installation in immersion fittings for measurement in open tanks or channels

Within the wide range of process adapters, subassemblies, flow fittings and immersion fittings it is easy to find the appropriate installation that fits the application (a wide choice of materials), the plant installation practice (a wide choice of process connections) and the maintenance procedures.

1.2 Unpacking and Checking

Upon delivery, unpack the sensor carefully and inspect it to ensure that it is not damaged during shipment. If damage is found, retain the original packing material and immediately notify the carrier and the relevant local Yokogawa Sales office. Make sure the Model Code and Serial Number on the sensor are the same as on the packing list. Also check if option(s) that were ordered, are included and correct.

1.3 Warranty and Service

Yokogawa products are guaranteed free from defects in workmanship and materials under normal use and service for a period of (typically) 12 months from the date of shipment from the manufacturer. Individual Sales organizations can deviate from the typical warranty period, and the conditions of sale relating to the original purchase order should be consulted. Damage caused by wear and tear, inadequate maintenance, corrosion, or by the effects of chemical processes is excluded from this warranty coverage. In the event of a warranty claim, the defective goods should be sent (freight paid) to the Service Department of the relevant Yokogawa Sales office for repair or replacement (at Yokogawa’s discretion).

The following information must be included in the letter accompanying the returned goods:

• Model Code and Serial Number.

• Original Purchase Order and Date.

• Length of time in service and description

of the process.

• Description of the fault and circumstances

of the failure.

• Process/environmental conditions that

may be related to the failure of the sensor.

• Statement as to whether warranty or non-

warranty service is requested.

• Complete shipping and billing instructions

for return of material, plus the name and phone number of a contact person that can be reached for further information.

• Clean Statement Returned goods that have been in contact with process fluids must be decontaminated and disinfected prior to shipment. Goods should carry a certificate to this effect, for the health and safety of our employees. Material Safety Data sheets must be included for all components of the process to which the sensor(options) have been exposed.
