PTU301 Combined Pressure, Humidity and Temperature Transmitter
The PTU301 provides precision-level barometric pressure, humidity and temperature measurement in one transmitter. The instrument is ideal for laboratories and engine test cells.The top-of-the-line PTU301 incorporates advanced Vaisala BAROCAP® and Vaisala HUMICAP® sensor technologies for highest precision and reliability.
The transmitter has a keypad and a large graphical display for convenient monitoring of the readings and trends, and changing transmitter settings. 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...+60°C (-40...+140°F) T
- Channel 3: 4...20 mA = 500...1100 hPa
- The transmitter is also equipped with an RS232C digital output.
The package includes:
- Calibration certificate (ISO9001 compliant, traceable to NIST)
- Cable bushing for max. 6.5 mm (PG7) cable
- Installation plate for transmitter, with humidity and temperature probe holder
- Universal AC power (100-240 VAC) with power cord
