The Best Alternative for the Discontinued Moore / Siemens 353 SLC Controller

Siemens has discontinued their 353 SLC controller. The 353 was used in many process applications for many years. It's discontinuation leaves many companies without an alternative.

Don't worry - you don't have to turn to eBay looking for spare parts? There's a better solution - the Yokogawa YS1700 PID loop controller. The YS1700 is a drop-in SLC replacement for the Siemens 353 and will keep you off of eBay.

The YS1700’s powerful function block programming allows for custom strategies to control many demanding processes such as boilers and steam generators, PH control, dosing control, and many other demanding plant processes. For more information, visit this site.

Understanding How Radiometric (Radiation-based) Level Measurement Works

Radiometric (also known as radiation-based) level measurement uses a very slightly radioactive isotope that emits focused gamma rays. A sensor, which is mounted on the opposite side of the vessel, receives this radiation. Because gamma rays are attenuated when penetrating matter, the sensor can calculate level, point level, density or mass flow from the intensity of the incoming radiation.

Advantages are:
  • Maximum operational reliability even in the harshest environments
  • Measurement is independent of pressure, temperature and product aggressiveness
  • Measuring system can be installed on the outside of a vessel during ongoing production
