Temperature/humidity Transmitter R320  (Japan Only) 

Ideal for use in chambers and ducts where the wind speed is always 3m/s or more

The following four types are available, taking into consideration the usage environment and conditions.

• R320 (standard type)
  The flange defines the boundary between the water pot and detecting element on the inside and terminal box and water tank on the outside.
• R321 (automatic water supply type)
  It is suitable for use in places with high temperatures and low humidity where water consumption is rapid.
  A continuous supply of water can be provided by connecting the pipes to a water supply or tank.
  There is a float switch inside the water pot to detect the water level, which opens and closes the solenoid valve to keep the water level constant.
• R322 (inner wall mounting type)
  The water pot, detecting element, terminal box, etc. are all structure inside.
  Instead of a water tank, it comes with a large water pot.
• R323 (internal pressure adjustment type)
  This is used when there is a pressure difference between the inside and outside, and is a standard type with a pressure equalizing tube attached to keep the water level in the water pot at a specified position.
