Vaisala HMT330180B091K - Humidity and Temperature Transmitter

The Vaisala HMT330180B091K is a highly advanced humidity and temperature transmitter designed to deliver precise environmental measurements in demanding industrial settings. Engineered with Vaisala’s renowned expertise in sensor technology, the HMT330180B091K offers robust input/output capacity, exceptional durability, and reliable performance metrics that make it ideal for critical applications in the power industry, petrochemical plants, and general automation systems. At its core, the Vaisala HMT330180B091K features a high-accuracy thin-film polymer sensor coupled with an integrated platinum resistance thermometer (Pt100), ensuring simultaneous and precise humidity and temperature readings. Its digital output supports multiple communication protocols, including 4–20 mA analog signals and Modbus RTU, facilitating seamless integration into existing control systems. This transmitter supports dual output signals, enabling real-time monitoring and control to optimize process conditions in complex industrial environments. The device operates reliably in harsh conditions, with an IP65-rated enclosure that protects it against dust and water ingress, and it maintains stable performance across a wide temperature range from -40 to +60 °C, enhancing operational uptime. In real-world scenarios, the Vaisala HMT330180B091K excels in the power industry by ensuring accurate humidity control within turbine generators and switchgear, where moisture levels critically impact equipment reliability and safety. 

In petrochemical facilities, it continuously monitors environmental parameters to prevent corrosion and product contamination in pipelines and storage tanks. Additionally, the transmitter’s robust design and precise measurements make it an excellent fit for general automation tasks such as HVAC system optimization and cleanroom environment monitoring, where consistent air quality is essential. Compared to other models within the Vaisala lineup, the HMT330180B091K stands out due to its combination of dual output capacity, rugged construction, and advanced sensor technology. For instance, while the Vaisala HMT330180B003K offers reliable humidity measurement, it lacks the extended temperature range and dual output flexibility of the HMT330180B091K. Similarly, the Vaisala HMT330180B093K provides comparable humidity sensing but does not match the communication versatility found in the B091K variant. For applications requiring more extensive environmental control, the Vaisala KeTop T200-M0A-Z20-WES7 offers integrated control capabilities, but the HMT330180B091K provides a more focused, high-precision sensing solution. Alongside the Vaisala HMT330180B091K, other Vaisala automation products such as the Vaisala PS 240 and Vaisala PS 244/B pressure transmitters enable comprehensive process monitoring, while the Vaisala DC 162/IP20/53151/03 data logger complements the system for detailed environmental data recording. The HMT330180B091K also pairs well with Vaisala’s broader sensor and control ecosystem. 

For example, the Vaisala KeTop C55-m00-AU1-DMG 87149/02 offers advanced operator interface solutions, facilitating straightforward configuration and diagnostics of the HMT330180B091K. The Vaisala HT4-221 humidity and temperature sensor can provide additional localized measurements, enhancing system redundancy and accuracy. In environments where both oxygen and humidity need monitoring, the Vaisala DO 321 / DO321/16/B oxygen meters integrate effectively with the HMT330180B091K, ensuring comprehensive atmospheric control. When deployed in power plants, petrochemical sites, or automated manufacturing lines, the application of HMT330180B091K in power industry, petrochemical, and general automation ensures superior environmental control, reducing downtime and enhancing safety. Its durable design significantly lowers maintenance costs compared to less robust alternatives, such as the Vaisala HT401-122-4/0, which—while offering quality sensing—is tailored for less demanding environments. In summary, the Vaisala HMT330180B091K combines precision measurement, durability, and versatile communication options to serve as a cornerstone sensor in industrial automation. Its ability to deliver reliable humidity and temperature data under extreme conditions makes it indispensable for critical infrastructure and process control. Alongside complementary Vaisala automation products like the Vaisala E-CPU-186B for processing, the Vaisala GVME-610-I/O for input/output expansion, and the Vaisala KeControl C2 102426 for control management, the HMT330180B091K forms part of a sophisticated, scalable solution for industrial automation challenges. For industries demanding high-performance environmental sensing, the Vaisala HMT330180B091K represents a top-tier choice, backed by Vaisala’s extensive experience and commitment to quality. Whether used independently or as part of a broader Vaisala system, it ensures precise, reliable data critical to optimizing operations and safeguarding equipment across power, petrochemical, and automation applications.
