1. PREFACE
1.1 Introduction
The sensor, model SC4A, SC41, SC42, SC49 and SX42, and associated fitting program 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 Instruction Manual.
Model SC4A sensors, available in a Stainless Steel or Titanium version with fixed cable or
Variopin connector, in combination with WU10/WE10-cable are intended for the low conductivity
applications. These sensors are designed in a convenient compact style, and can be inserted
directly in process pipework using available fittings or adapters.
Model SC41, SC42 and SC49 sensors, available in various materials such as Epoxy, Stainless
Steel, PTFE and PVDF, are intended to suit most process conditions. The sensors are provided
either with a Amphenol connector to fit the Yokogawa WU40 cable or Variopin connector to fit with
Yokogawa WU10/WE10-cable. A wide range of flow and immersion fittings makes it possible to
install the sensors in a permanent or semi-permanent location.
Model SX42 sensors have a Stainless Steel body and ceramic insulation, especially designed to
withstand high temperatures and high pressures. The flanged model has an integral connection box,
the threaded models are provided with a Amphenol connector to fit the Yokogawa WU40 cable or
Variopin connector to fit with Yokogawa WU10/WE10-cable.
All sensors have a pre-calibrated cell constant and a built-in temperature element for automatic
temperature compensation. Sensors with the Variopin connector are equipped with an ID-chip
in which callibration information is stored for easy setup when connected to a SENCOM Smart
Adapter model SA11-C1. For metal sensors a 3.1 material certificate is included. The sensors,
except those equipped with Variopin connector, are ATEX certified for installation in zone 0
environments when connected to a certified intrinsically safe Yokogawa analyser, model SC202S
or FLXA21 or a certified intrinsically safe circuit with defined output parameters (see General
Specifications of each sensor for details).
1.2 Unpacking and Checking
Upon delivery, unpack the sensor carefully and inspect it to ensure that it is not damaged during ship-
ment. 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 nonwarranty 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.

2.2.1. Typical installation SC4A-*-AD with standard options
The SC4A-*-AD sensor can be installed in the process using optional ¾” NPT adapters. These
adapters are available in Stainless Steel (/PS) and in PVDF (/PF); see figure 3 for the mounting
sequence. The sensor can also be installed in an optional Stainless Steel flow fitting (/FF) using
option /PS, see figure 4 for details.

2.2.2. Typical installation SC4A-E-SA (SB, SC) with standard options / spare parts
The typical installation of the SC4A-E-SA sensor is done by using a standardized 25 mm port.
Stainless Steel welding sockets are available as straight version (spare part /SA1) or 15° angled
version (spare part /SA2). Both versions are delivered with mounting nut.
In figure 5 an example is shown how to install the sensor using spare part /SA1.
Sensors SC4A-E-SB and SC4A-E-SC are installed by tri-clamp method.
For the SB version two Stainless Steel tri-clamps are available, in a 1” size
(spare part /SB1) or in a 1½“ size (spare part /SB2).
The SC version has just one Stainless Steel tri-clamp in a 2” size (spare part /SC1).

2.4. Wiring SC4A sensors
The SC4A sensors are provided with a fixed sensor cable or Variopin connector to fit the WU10/WE10
cable up to 20 meters. When a longer cable run is necessary (maximum cable run is 60 meters), this
can be done by using the WF10 extension cable in combination with the BA10 connection box. The
connection of the integral cable and WF10 cable to the Yokogawa Contact Conductivity analyser are
given in table 3.
