Michell Instruments PC62 / PC62V Relative Humidity & Temperature Probe

The Michell Instruments PC62 / PC62V relative humidity & temperature probes are designed for highly accurate RH and temperature measurements in precision manufacturing applications. The probes are also available with calculated absolute humidity, dew point and web bulb temperature output.

The PC62 has a digital output that can be directly connected to a two-wire RS485 network or a standard serial RS232 interface, depending on the version. The probe with an RS232 output communicates with any computer or PLC equipped with an RS232 interface. When ordered with an RS485 output, the PC62 becomes an addressable transmitter enabling a maximum of 32 units to be connected to a single two-wire bus. The transmitter acts as a slave and will only provide data output when requested by the system. The probe also features digital zero and span adjust, robust housing and a connector for quick and easy installation. The PC62V offers 0-1V, 0-5V or 0-10V analog output.
