Mercury-Free Sensors by Dynisco
“Mercury-free sensors” from Dynisco are pressure and process sensors designed without mercury or other hazardous fill media. Instead, they use alternative fill fluids — or in some sensor designs no fill medium at all. That makes them more environmentally friendly, safer to handle, and especially suitable for sensitive applications such as food production, medical or pharmaceutical processing. Despite the elimination of hazardous media, they offer high precision, robustness and meet industrial standards for pressure, temperature and chemical resistance.
Mercury-free sensors enable process or melt pressure measurement without the hazards of traditional mercury-filled sensors. They provide standardized output signals (e.g. 4–20 mA, mV/V, 0–5 V / 0–10 V), resist corrosion and high temperature, and can be integrated into existing plants or control systems — ideal for plastic extrusion, injection molding or other industrial processes under demanding conditions.
Questions & Answers on Mercury-Free Sensors
What does “mercury-free” mean?
That the sensor does not use mercury as a filling medium — no toxic or environmentally harmful fluid is involved in pressure transmission.
Why choose mercury-free sensors?
They are safer, easier to handle and dispose of, comply with environmental and safety regulations, and suitable for sensitive industries such as food or medical applications.
Which types of sensors are offered mercury-free?
Pressure / melt-pressure sensors and transducers, including models with alternative fill or no fill — e.g. the “Vertex” line and other Mercury-Free / Alternative-Fill series.
Where are these sensors typically used?
In plastic processing (extrusion, injection molding), polymer production, food or medical application, packaging, and any industry where contamination, safety or environmental impact matters.
What output signals do they provide?
Depending on the sensor: mV/V, 4–20 mA, 0–5 V, 0–10 V (or similar standard signals), compatible with data acquisition, PLC or control systems.
How do they perform under high pressure / temperature?
They are engineered for industrial use — using robust diaphragms (e.g. coated Inconel or stainless steel), temperature and pressure resistance, corrosion resistance and long-term durability.
Is integration into existing installations easy?
Yes — they use standard process fittings and output signals, making retrofitting or initial installation straightforward and compatible with many control and monitoring systems.
Are there drawbacks compared to traditional sensors?
The main difference lies in the fill medium (or lack thereof); performance in terms of accuracy, response and durability remains comparable. In manchen Spezialfällen kann jedoch die Auswahl eines geeigneten Modells entscheidend sein (z. B. Temperaturbereich, Medium, Signalart).
When is a mercury-free sensor especially recommended?
When environmental safety, hygiene standards, contamination prevention or regulatory compliance are important — e.g. in food or medical processing plants, sustainable manufacturing, or when working under strict safety and environmental guidelines.
