High Accuracy Humidity & Temperature Transmitter - Wall Mounted With Display HMW90

The Vaisala Indigo, Indigo 510, Indigo 520 transmitter has 4 analog channels that can be configured to mA or voltage type and 2 configurable relays. The Vaisala Indigo510 has 2 analog channels. Any of the output parameters from the connected probes can be assigned to control the analog channels and relays. Digital output protocol is Modbus TCP/IP over Ethernet. Besides Modbus TCP/IP, the transmitter's Ethernet connection provides a web interface and cyber-security that meets the modern standards

The touchscreen display provides local data visualization and easy access to probe configuration. The transmitter also extends the options for connectivity, supply voltage and wiring, compared to using just a smart probe. It also provides mechanical support when wall-mount probe installation is preferred.​ Rugged IP66- and NEMA4-rated  metal enclosure ensures reliable performance even in the harshest conditions.

The Indigo-compatible smart probes include humidity probes (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point probes (DMP5, DMP6, DMP7 and DMP8),  carbon dioxide probes (GMP251 and GMP252), moisture in oil probe (MMP8), temperature probe (TMP1), and vaporized hydrogen peroxide probes (HPP270). The Indigo520 is also compatible with MHT410 Moisture, Hydrogen and Temperature Transmitter for power transformer online monitoring

The Indigo520 dual-probe support allows simultaneous measurements with two Vaisala Indigo-compatible probes for humidity, temperature, dew point temperature, carbon dioxide, vaporized hydrogen peroxide, and moisture in oil measurements. If you need just one probe, the Indigo510 is an ideal choice.

Vaisala INTERCAP® Humidity and Temperature Transmitter Series HMD80 HMW80 HMS80 measure relative humidity and temperature in various building automation applications. Transmitters combine easy installation and reliable operation with a low requirement for maintenance.

The versatile Vaisala HMDW80 series includes transmitters for wall and duct mounting, IP65-classified transmitters for humid areas, and transmitters with a radiation shield for outdoor use. It also includes temperature-only transmitters and transmitters with an optional display.

Calculated humidity parameters –dew point temperature, wet bulb temperature, and enthalpy are also available.

Vaisala HMT330 series are easy-to-use transmitters for demanding industrial and air conditioning applications. The transmitters measure relative humidity and temperature and from these calculate dew point and wet bulb temperature, mixing ratio and absolute humidity.

They can be configured to the customer's requirements on the production line, but configuration and parameters can also be set by the user. The series has both analogue and serial outputs as well as several options: different cable lengths, power supply modules and serial interface modules as well as a local display.

• for environmental chambers including vacuum and high pressure chamber

Vaisala Humidity and Temperature Module HMM170 is a robust open frame transmitter for integration into environmental chambers that need accurate and reliable measurement even in demanding conditions including vacuum or high pressure.

The module is built to last for years and it is easy to integrate into the chamber and the circuit board. Both digital and three configurable analog output channels are available, ensuring compatibility for most chamber types. In addition to relative humidity and temperature, dew point and other calculated parameters are available.

The HMM170 provides a digital RS-485/Modbus RTU output and three freely configurable analog output channels. The module provides relative humidity, temperature, dew point, and other calculated parameters.

Vaisala HMT360 humidity and temperature transmitter is designed for use in potentially explosive atmospheres. The electronics are designed so that the transmitter is intrinsically safe. The whole transmitter can be installed directly into an explosive area, even into areas classified as having a constant risk of explosion (Zone 0). HMT360 fulfils all requirements of current standards. The microprocessor-based HMT360 is easy to install, maintain and calibrate due to its modular structure. The interchangeable probes are easy to remove and enable on-site calibration. They make the HMT360 series versatile and ensure its suitability for almost any application

Also suitable for measuring water activity of Jet Fuel

The current loop-powered, two-wire transmitter is called the Vaisala HMT120 and the three-wire transmitter - with voltage and serial line outputs as well as a relay - is called the Vaisala HMT130. The new transmitters utilize the fully interchangeable HMP110 probe.

The transmitters replace with enhanced features the currently very successful HMT100 transmitters. The HMT120 and HMT130 transmitters are especially designed for cleanroom continuous monitoring systems and are very easy to clean. The housing is also durable for continuous exposure of cleanroom cleaning agents and the interchangeable measurement probe is equipped with the latest humidity sensor technology, the HUMICAP180R.

• for environmental chambers

The Vaisala HUMICAP® Humidity Module HMM100 is an open frame module for integration into environmental chambers. The modules provide a single analog output channel for relative humidity (RH) or dew point (Td).

Practically maintenance-free HMM100 is an open frame module for integration into environmental chambers. Excellent measurement accuracy with Vaisala HUMICAP® 180R sensor.
