What is the PLAATO fermentation sensor?
Our PLAATO Fermentation sensors give you a fermentation monitoring system designed to help breweries achieve consistency, efficiency and quality. Our sensors measure density, temperature and fermentation progress in real time. They connect to PLAATO Insights, so you can constantly monitor your fermentation and take action when you need to.
How the PLAATO fermentation sensor works
The PLAATO Fermentation sensor uses tuning fork technology to measure density and temperature in real time. Made from 304 graded stainless steel, it ensures quality and durability while maintaining purity by only contacting the fermenting liquid.
The PLAATO Fermentation Sensor integrates effortlessly with fermenters using a 1.5” tri-clamp connection. Need to retain a sample port? Adapters and T-connectors are available to fit your setup. The sensor is CIP compatible, though many brewers opt to remove the sensor for cleaning.
Why Choose PLAATO
Fermentation sensors are easy to compare on a spec sheet. They’re harder to compare on what happens six months into daily use in a working cellar. Here’s what tends to matter most once a sensor is actually living on your tanks.
Not over-engineered
Sensors with more measurement points often need more upkeep. Inline pH sensing is a good example: it has to stay wet at all times, so it can’t sit in an empty tank between batches, and it needs frequent recalibration. PLAATO monitors just density and temperature, the two numbers that actually show where a fermentation stands, which is why it’s genuinely CIP compatible: leave it in the tank between batches, no maintenance routine required.
No contamination risk
Threading creates crevices where residue and bacteria can collect. The PLAATO Fermentation Sensor has none: one continuous piece of 304 food-grade stainless steel, with nothing to loosen or trap residue.
Slim enough for the ports you already have
At 21mm, the PLAATO Fermentation Sensor fits standard sample ports without a retrofit, and it’s slim enough to pair with a T-connector so your sample tap can stay on the same port.
Priced to instrument every tank, not just a few
Fermentation sensors usually cost enough to limit you to a handful of priority tanks. PLAATO delivers the same core measurement quality at roughly a quarter of the price, making it realistic to instrument every fermenter instead of just a few.
Proven where it counts: in working breweries
More than 300 breweries in 30+ countries run on PLAATO sensors today. That track record, across tank sizes, cleaning regimens, and climates, is years of field testing behind it, not a first-generation product still working out its failure modes.

“We use 3/4 less CO2 than we used to, which is equivalent to $400-500 a month for us. So even just with that, PLAATO pays for itself not including man hours, testing, and wasted beer."
