pi safety: Reliable technology for industrial applications
– install – connect – done!
pi safety industrial components have been specially developed for use in non-explosive areas. Whether in ventilation, building or production technology, our high-quality actuators, sensors and volume flow controllers impress with their maintenance-free operation, simple “plug-and-play” system integration and high precision in operation. Thanks to their modular design and factory configuration, pi safety products can be flexibly integrated into almost any industrial automation system – reliably, quickly, efficiently and durably

What advantages do pi safety components offer compared to conventional industrial products?
Modular two-component system:
greatly simplifies installation – without having to dismantle the entire device.
Plug-and-play commissioning:
pre-parameterized components save time during installation and commissioning – mount, connect, done!
Robust industrial suitability:
high IP protection classes, vibration-resistant electronics, and tested long-term stability.
Short delivery times and direct support:
fast availability without long distribution or service channels.
For which industrial applications are pi safety products suitable?
pi safety's industrial products are specially designed for applications outside potentially explosive areas. Typical areas of application are:
Air conditioning and ventilation technology (HVAC)
Process air and filter systems
Machine and plant engineering
Production and conveyor technology
Building control systems
Thanks to their compact design, robust housing (IP66), and maintenance-free operation, these devices are ideal for continuous industrial use—even in difficult environmental conditions such as dust, moisture, seawater, or temperature fluctuations.
FAQ about industrial applications of pi safety
At the heart of many pi safety products is the two-component system:
• Base unit (e.g., sensor or actuator)
• Connection & interface box
Both units can be mounted separately and handled independently of each other during maintenance or replacement. Advantages for industry:
• Significantly reduced downtime during service calls
• No need to open or disconnect entire devices
This means a real gain in efficiency, especially in hard-to-reach installation locations or tight maintenance windows.
- The actuators are controlled with 4-20 mA or 0-10 V.
- The TR.Ex transmitter provides feedback in 4-20 mA or 0-10 V.
- The SW.Ex switching amplifier has two relay outputs.
Yes – pi safety volume flow controllers and sensors are used in particular in industrial ventilation technology and filter systems. They enable:
- Precise control of air volumes
- Energy-efficient control of ventilation and extraction
Thanks to their high repeat accuracy and long-term stability, the devices are also suitable for systems with variable volume flow control (VVS).
All industrial products have at least IP66 protection, meaning they are:
- dustproof
- protected against powerful water jets
Depending on the product, the permissible temperature range is between –40°C and +70°C, ideal for technical rooms, outdoor areas, or production facilities without air conditioning.
pi safety manufactures in Germany and relies on a lean supply chain. This means that:
- standard products are often available within a few working days
- custom configurations are available on request
- replacement and service parts can be delivered quickly
This is a major advantage for plant engineers who need short project deadlines and reliable delivery partners.
We also offer special solutions on request. However, these are usually not necessary, as our products have a very wide range of capabilities.
