HMT330 Series Humidity and Temperature Transmitters for Demanding Humidity Measurement
The Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT330 is designed for demanding applications where stable measurement and wide customization is important.
Six models for demanding applications:
HMT331 for wall mounting
HMT333 for duct mounting and tight spaces
HMT334 for high pressures up to 100 bar and vacuum conditions
HMT335 for high temperatures
HMT337 for high humidity and meteorological applications
HMT338 for pressurized pipelines up to 40 bar
Warmed probe for superior performance in condensing environments
Shows measurement trends and history graphically
Corrosion resistant IP65 housing
NIST traceable (certificate included)
Optional integrated data logging, with over four years of measured history
LAN and WLAN communication options
Compatible with the Vaisala Continuous Monitoring System
Features/Benefits
for remote probe installations in demanding HVAC applications
for temperatures -40 ... +80 °C (-40 ... +176 °F) or -40 ... +120 °C (-40 ... +248 °F)
Small thermal mass - fast response to temperature changes
Application examples: cleanrooms, pharmaceutical processes, greenhouses, environmental chambers
The Vaisala HUMICAP® Humidity and Temperature Transmitter HMT333 is a versatile instrument for applications where a small remote probe is needed.
Flexible Installation
To install the probe in ducts, channels and through walls, an installation kit is available with a stainless steel flange, lead-through piece, and steel support bar. HMT333 has two probe cable options available, a flexible one that withstands heat up to +80° C, and a durable cable that withstands heat up to +120° C. Both cable options are available in lengths of 2, 5, and 10 meters.
Outputs and Power Supply Options for Every Need
The output options include three analog outputs, RS-232, RS-485, and alarm relays. The voltage supply range is from 10 to 35 VDC. With an additional module, the transmitter can be connected to all universal mains AC supplies. The input/output cable can be fed through the back of the transmitter, which is a useful feature, especially for installations in cleanrooms. for outdoor environments, the DTR502B solar radiation shield provides protection for the probe. The shield can be installed on a pole, a beam or a flat surface.
for Moderate Humidities and Temperatures
The HMT333 is typically used in demanding HVAC applications such as cleanrooms, pharmaceutical processes, and greenhouses, or in processes of moderate temperature. for environments with continuously high humidity, the HMT337 with a warmed, vapor-tight and stainless steel probe is recommended.
NOTE: The part number is built based on the options required. Please follow the link below to see the configurator and provide us with a complete part number for a price quote.
