Vaisala has released a next-generation humidity and temperature transmitter series to take advantage of improvements in technology and to reach and exceed current hazardous area regulations.


The new Vaisala HUMICAP Intrinsically Safe HMT370EX Humidity and Temperature Transmitter Series builds on the HMT360 series with a more robust and easy-to-use design.


“We are pleased to introduce the HMT370EX series which offers improved user experience, better corrosion resistance, and the latest Vaisala humidity measurement performance. It’s a true successor to our trusted HMT360 product series, and it can be effortlessly installed into existing systems,” says Juhani Lehto, product manager, Vaisala Industrial Measurements.


The series is intended particularly for hazardous and explosive environments. The complete transmitter can be installed directly in explosive areas, up to zone 0 and zone 20.


“HMT370EX operates safely and reliably even in the most hazardous environments, with no need for additional protective enclosures. Thanks to its rugged display, the transmitter can withstand continuous exposure to potentially explosive areas that contain flammable gases or dust,” Lehto continues.


Typical applications for the device comprise paint booths in the automotive industry, chemical plants and processes, baking industry, hydrogen cooled generators in electricity generation, oil and gas drilling platforms, pharmaceuticals manufacturing, fuel tanks, and storage.
