High-Precision Low-Temperature Measurement with the Temp-485-Pt100 Frost2
Accurate monitoring of extremely low temperatures in demanding industrial environments requires sensors that are both robust and highly precise. The Temp-485-Pt100 Frost2 is a temperature sensor specifically developed for low-temperature applications and equipped with an external Pt100 probe capable of measuring temperatures from –190 °C to +150 °C.
With its rugged design, IP65 rating (converter), IP67 rating (probe), and compatibility with the Poseidon2 4002, this sensor is ideal for industrial environments where precision and reliability are required under extreme conditions. Below is a detailed description of the Temp-485-Pt100 Frost2, including its technical specifications, applications, and advantages.
Overview of the Temp-485-Pt100 Frost2
The Temp-485-Pt100 Frost2 is an industrial temperature sensor designed specifically for cryogenic and low-temperature applications. The external Pt100 probe, housed in a sturdy 50 mm stainless steel (17240) enclosure, is connected to the converter via a 2-meter PTFE cable.
This cable allows for flexible positioning of the probe, making the sensor particularly suitable for hard-to-reach measurement points. The converter is enclosed in a wall-mountable casing with IP65 protection, shielding it from dust and water jets, while the IP67-rated probe operates reliably even in wet environments.
The sensor communicates via an RS-485 interface using a straightforward ASCII protocol (9600Bd 8N1), allowing for stable data transmission over long distances. It is specially designed for integration with the Poseidon2 4002 monitoring system, which handles both power supply (12–24 V) and data transmission. Alternatively, the sensor can be powered by an external 10–35 V DC source with reverse polarity protection. With compact dimensions of 114 × 65 × 35 mm (converter) and a total weight of 165 g, the Temp-485-Pt100 Frost2 is easy to install and highly versatile.
