These sensor housings are designed to be used with model F-235, F-285, F-635, F-695, F-835 and F-895 Metric FermProbes® and models D540 or D545 12 mm OxyProbe® II dissolved oxygen sensors. They are also compatible with any 12 mm sensor that has Pg13.5 threads. These housings fit nearly all standard 25 mm ports found on production and pilot plant vessels. Different housing lengths are available to accommodate various application or vessel requirements.

The sensor threads directly into this metric housing, eliminating the threaded retainer ring. In order to prevent twisting the cable, the metric FermProbes have a detachable cable.

Guarded and unguarded versions are also available. Using a guarded housing is highly recommended for pH electrodes to provide maximum protection against damage to the sensing bulb. However, highly viscous media is prone to clog the guard.

Specification

  • 316L stainless steel construction.
  • Serialized for traceability to mill steel specifications.
  • RA32 finish with electropolish on all wetted parts.
  • Permanently secured port retainer ring for additional operator safety.

Guarded Housings

Housing Model Class Typical Vessel Insertion Length Used With pH Electrode Models Used With Electrode Length Housing Part Number
Model 335 D 52 mm (2.1″) F-235, F-285, F-635, F-695, F-835, F-895, 120 mm 335-61-H070
Model 335 F 128 mm (5.0″) F-235, F-285, F-635, F-695, F-835, F-895, 200 mm 335-61-H150

 

  1. Confirm the opening is a standard 25 mm side port.
  2. Determine whether the application will permit the use of a bulb guard on the housing. The bulb guard is highly recommended for all applications except when the media is very viscous. Highly viscous media is prone to clog the guard.
  3. Determine how far the housing and sensor should extend into the vessel.
  4. Confirm the sensor is a metric FermProbe, models D540 or D545 OxyProbe II or European sensor with Pg13.5 threads.
