SE 557
Refillable pH Sensor

The SE 557 refillable pH sensor is ideal for high-precision measurements. The pressurized liquid electrolyte is self-cleaning.

  • Extensive measuring range for pH and temperature
  • Refillable liquid electrolyte
  • Self-cleaning due to pressurization
  • CIP- and SIP-capable
Description

The SE 557 refillable pH sensor with Memosens digital technology is an ideal sensor for liquids with low ionic activity. In addition, the pressurization of the glass body makes this refillable sensor self-cleaning. An integrated NTC 30K temperature element accurately compensates for the process temperature. The SE 557 and its double ceramic junctions make this pH sensor highly accurate. An analog version of this sensor is also available.

Additionally, this refillable pH sensor is suitable to use with any Memosens transmitter.

Applications for the SE 557 Refillable pH Sensor

  • Boiler feedwater

  • Water for injection (WFI)

  • Semiconductor production

  • Difficult process media requiring high measurement stability

 

SE 557 with Memosens Technology

Memosens sensors provide several benefits regarding ease of use and reduction of operating costs, such as:

  • The submersible, inductive connection removes measurement influence from moisture and humidity. This is commonly present in CIP and SIP applications.

  • Galvanically isolated so there is no measurement influence from electrical noise or ground loops. This is especially beneficial in open basins when using plastic holders.

  • Technicians can perform calibrations and diagnostics in the shop or lab. As a result, this reduces field maintenance time and process downtime.
