Vaisala HMT335 Humidity and Temperature Transmitter with Remote Probe for Temperatures Up to +180°C (+356°F)

Product Description

The HMT335 is a top-of-the-line versatile instrument with a stainless steel probe designed to withstand high temperatures. The HMT335 is ideal for duct measurements as the probe tolerates mechanical stress and withstands high flow rates. For example, the HMT335 can be used in hot drying processes. The Vaisala HUMICAP® Humidity and Temperature Transmitter HMT330 series incorporates Vaisala’s 40 years of experience in industrial humidity measurement.

The instrument offers a wide variety of different psychrometric units, including dew point, enthalpy, wet bulb temperature, absolute humidity, and mixing ratio.

The transmitter has a keypad and a large graphical display for convenient monitoring of the reading and transmitter setting changes. For example both output signal type (voltage or current) and scaling can easily be changed by the user.

Analog outputs are preset at the factory to:

  • Channel 1: 4…20 mA = 0...100% RH
  • Channel 2: 4...20 mA = -40...+180°C (-40...+356°F) T

The package includes:

  • 25 cm (10") stainless steel probe with 2 m (6.5 ft) cable
  • Installation flange, allowing an adjustable installation depth for the probe
  • Calibration certificate (ISO9001 compliant, traceable to NIST)
  • M20x1.5 cable gland and NPT1/2" conduit fitting included to facilitate wiring
  • User's Guide in English
