Inline pH & ORP Sensor Fittings and Flow Cells
Every Turtle Tough pH and ORP sensor can be installed inline: choose the inline method when you order. For a sensor you take out to clean and calibrate, use a twist-lock, sanitary tri-clamp or hot-tap fitting rather than threading it in and out, which twists the cable and can damage the connections in the back of the sensor. Twist-lock and tri-clamp fittings need the line isolated to remove the sensor; hot-tap is the only method that works while the line is live.
Choosing an inline fitting
| Fitting | Connection | Pressure | Best for |
|---|---|---|---|
| Inline Twistlock Hardware | Bayonet quick disconnect; 1" MNPT into a 1" FNPT pipe tee | Kynar 50 psig; CPVC or PEEK 100 psig | Fast insertion and removal of 1" twist-lock sensors |
| Quick Release Tri-clamp Inline Sensor Adapter | Retrofits any sensor with a 3/4" MNPT front thread; 2" flange; 316SS | Up to 100 psig | Removing an inline sensor without unscrewing it from the process |
| Inline Sanitary Sensor Holder | Tri-Clover 1.5", 2" or 2.5"; FDA 3A grade 316SS | - | Sanitary processes, with quick-connect plugs for easy calibration and cleaning |
| Inline Front-end | 1 1/4" threaded fitting with hex flats | Recommended above 100 psi | High-pressure or aggressive applications where the sensor needs extra protection |
| Flow Cell | Clear body, tangential inlet, sample valve | - | Side-stream pH and ORP measurement at a constant sample velocity |
| Multi Sensor Stainless Steel Flow Cell | 316SS body | - | Several smart sensors (pH, ORP, turbidity, TSS) on one steady side stream |
| Low Flow Panel | Custom side stream with control of pressure, flow and temperature | Custom | Processes outside the sensor's operating limits |
| Height-adjustable insertion rods (TOUGH, ULTRA) | 316SS rod, 600 to 1500 mm, with tri-clamp adapter | - | Variable-depth insertion from the top of a tank or vessel |
Inline installation tips
- Inline sensors have their temperature compensation element at the tip, so they read the process temperature. A sensor ordered as fully submersible has it in the back end, so used inline it reads ambient temperature.
- Avoid plastic pipework where you can: static and stray current cause erratic readings. Otherwise install the sensor in a metallic housing that can be earthed, or earth the pipework another way.
- Outdoors, seal the back of the sensor in conduit, or order a waterproofing option such as Cable Protection. Waterproofing can only be added when the sensor is made.
