Vaisala launches new measurement probe for improved dry room control
Vaisala launched today the new DMP1 Dew Point and Temperature Probe to monitor environmental conditions in critical manufacturing rooms and spaces. With dew point measurement capability down to -70°C, and a rapid response, hundreds of times faster than other competing measurement technologies, the new compact DMP1 is ideal for dry rooms.
The new Vaisala DMP1 probe provides precise measurements in demanding dry processing conditions, such as those found in lithium-ion battery production, where humidity control is critical to the performance of manufactured batteries. Employing advanced measurement technology, the DMP1 ensures that dew point conditions remain as specified in all areas of a manufacturing dry room, thereby helping to maintain both product quality and manufacturing safety.
The DMP1 can be easily integrated into centralized production, safety, and quality monitoring systems.
“The fast response of the new probe means that customers’ control systems are able to respond quickly, in a timely manner, ensuring the protection of product quality and safety,” says Juhani Lehto, Product Manager for Precision Instruments, Vaisala.
“This means that customers can control any deviations in the dry room dew point efficiently. Quick reaction times translate into improved workplace safety in battery manufacturing, maintaining high product quality as well as avoiding waste in the production process.”
Designed for measurement stability, with long calibration cycles, the DMP1 has a low maintenance requirement and can withstand accidental humidity spikes caused by humans, machines, or external air conditions.
Improved visibility and control of the entire dry room
The DMP1 is a part of the modular Vaisala Indigo measurement ecosystem, offering plug-and-play compatibility with connected smart devices. For example, it can be connected to an Indigo300 transmitter to display data locally and transmit measurement values to automation and control systems. The probe can also be connected to an Indigo80 handheld device for maintenance work, and interchangeable probes mean that downtime is minimized and service work is simplified.
Summarizing, Lehto says: “In the past, dew point control in dry rooms has been limited by bulky sensors with a limited measurement range and a slow response. The DMP1 probe is therefore a major step forward because it resolves these issues, providing process managers with greater visibility of environmental conditions and more time to respond when conditions deviate from ideal.”
