Yokogawa Model FU20 Widebody Type PH ORP Sensor PH21 PH4 OR4

Yokogawa Model FU20 Widebody Type pH/ORP Sensor PH21 PH4/OR4

A family of the wide body sensor is available for application in a wide variety of processes. The sensors share the same valuable features:

• Long life saturated Ag/AgCl reference system.

• PTFE reference diaphragm to prevent fouling and reduce measurement error.

• Double junction combined with ion-trap to prolong the life of the reference probe, even in chemically unfavorable environments.

• Integral Pt1000 element for accurate temperature measurements.

• Platinum ORP/LE electrode for accurate simultaneous pHand ORP measurements.

• Polymerized electrolyte to extend the sensors life time.

• Versatile in-line, immersion or off-line installation.

The FU20 combination sensor shows how Yokogawa applies the motto “Simply the Best” to sensor technology. The wide body sensors (26 mm diameter) hold four separate measuring elements in one unbreakable and chemical resistant PPS 40GF body. Installation is simple with the integrated industrial 3/4” tapered thread. Temperature fluctuations are compensated to extend the sensor life. The FU20 is targeted at those applications where simplicity will result in accurate and reliable pH- or redox measurements. This means that in 90% of the known applications, this sensor will be an excellent choice. In general purpose applications running at constant pressure and temperature the FU20 sensor has proven it use for years. In the standard configuration the wide body sensors hold four separate measuring elements in one unbreakable body made of PPS 40GF. This sensor offers a cost effective and rigid solution to the users. In strong acidic applications and in In cases where the chemical compatibility of PPS does not address the process needs, the FTD version made in a PVDF body offers the required solution. The additional chemical compatibility offered by the PVDF version addresses the needs in several applications.

The FU20 widebody type pH/ORP sensors are available with VP connector. This makes installation a lot easier. All sensors are delivered with a Quality Certificate.

In addition to our analogue sensors Yokogawa delivers a platform consisting of so called SMART sensors in combinaton with the SENCOM SMART adapter SA11. In the SENCOM platform digital functionality allows:

• Perform off-line calibration reducing process impact.

• Enable easier asset management

• Enable easier statistical process control

• Easier monitoring of extreme conditions during use.

For additional information about SENCOM and its benefits request you to check the applicable GS-document number GS 12A06S01-01Z1. This document is available from our website and through our regional offices.
