MDA 410 | 412 | TDA 412 (NaK)
The MDA 410 series is the ideal choice for the food and pharmaceutical industries. The sensors are filled with mercury-free NaK (potassium sodium) and meet FDA and USDA requirements. The combination of NaK filling and Inconel membrane enables accurate pressure measurement in processes with temperatures up to 530°C. The sensors are characterized by their excellent repeatability and reliability. It is supplied with a connection to the 6-pin Bendix connector for easy handling. MDA 410 is the most used mercury-free pressure sensor with mV/V output signal. The version with temperature sensor can be found under the designation TDA 412.
