Hygienic / Life Sciences › Quick Connect Sensor Program

The Quick Connect Sensor Program

The Quick Connect sensor program is a modular hygienic temperature sensor platform that allows calibration and sensor replacement without opening the process, without tools and without production stop. Dedicated to the pharma industry and food & beverage.

The principle

Calibration without opening the process

In GMP-regulated production, temperature sensors must be calibrated on a fixed schedule. Traditionally that means stopping production, opening the line and recleaning. Quick Connect removes all three steps.

1
Install once

The pocket is clamped or welded into the line — in-line pockets arrive pre-welded in their own pipe section, pressure-tested to 40 bar and ready for orbital welding, so no certified welds or radiographic testing on site. The process connection stays in place — you never remove it to reach the sensor.

2
Click the insert out

The measuring insert releases through the tool-free bayonet coupling in seconds. The process stays closed and the hygienic barrier stays intact.

3
Swap or recalibrate

Click a pre-calibrated spare insert in, and the measuring point is back in service in minutes — or recalibrate the insert wherever your calibration routine runs, at the line or in the lab. The process stays closed either way.

The platform

One coupling — four ways into your process

Every Quick Connect sensor is a pocket, a measuring insert and a head. What changes is how the pocket sits in your process — choose the access that fits your line.

Quick Connect sensor RT-BCQ with clamp pocket
ClampInto a Tri-Clamp fitting

The sensor’s clamp pocket sits in a standard Tri-Clamp fitting — ¾" APC, 1½" DN38 or 2" DN51 (ISO 2852). RT-BCQ and RT-BCQ-D are delivered as head, measuring insert and clamp pocket in one unit, ready to mount.

Quick Connect in-line thermowell — pocket pre-welded in its own pipe section
In-lineFor small-bore pipes

For small-bore pipes where a standard pocket does not fit. The pocket arrives pre-welded in its own pipe section, pressure-tested to 40 bar and ready for orbital welding into the line — no certified welds or radiographic testing on site.

Quick Connect weld-in thermowell for pipe and vessel walls
Weld-inInto pipe or vessel walls

Welded directly into the pipe or vessel wall and matched to the 167 mm measuring insert — with the same bayonet coupling on top.

Quick Connect clamp-on temperature sensor mounted on the outside of a pipe
Non-invasiveOn the outside of the pipe

Nothing enters the process. The clamp-on sensors measure on the outside of the pipe and lift off through the same quick-release coupling for calibration — with head or with cable.

The products

Seven products, one program

Sensors, inserts and pockets connect through the same coupling and share standardised insert lengths — components combine freely and spare-part inventory stays small.

Frequently asked questions

What is a quick connect temperature sensor?

A quick connect temperature sensor is a hygienic sensor where the measuring insert connects to the pocket through a tool-free coupling. The insert can be removed for calibration or replacement while the process connection stays in place — no production stop, no opening of the line, no recleaning.

Can the measuring insert be replaced during operation?

Yes. The bayonet coupling releases the insert while the pocket stays in the closed, pressurised process. The hygienic barrier is not broken, so production continues and no CIP cycle is needed afterwards.

Which products make up the Quick Connect program?

Seven products: the RT-BCQ temperature sensor, the RT-BCQ-D temperature sensor with display, the RT-BCQ-IN measuring insert, the in-line thermowell for small-bore pipes, the weld-in thermowell for pipe and vessel walls, and the clamp-on sensors with head and with cable — plus head-mounted transmitters.

Can sensors be installed without certified welding on site?

Yes. In-line thermowells are delivered pre-welded and pressure-tested to 40 bar, ready for orbital welding — no on-site certified welds or radiographic testing. Once installed, sensors are replaced tool-free via the Quick Connect coupling.

What materials and surface finish are used?

Media-contact parts are AISI 316L stainless steel (EN 1.4404), the standard hygienic grade. Duplex stainless steel is available on request for aggressive media. Surfaces are mechanically polished to < 0.8 µm Ra as standard, with electropolishing to < 0.5 µm Ra available — minimising bacterial adhesion and supporting CIP/SIP cleaning.

How is calibration handled?

The insert clicks out without tools while the pocket stays in the closed process — so calibration fits the routine you already run: recalibrate the insert at the line or in the lab, or click a spare in and keep the point in service. Standardised insert lengths mean one spare covers many points.

Does Quick Connect reduce spare-part inventory?

Yes. Inserts come in standardised lengths, so one spare insert type covers many measuring points — instead of one dedicated spare sensor per installation.
