Humidity and Temperature Probe with Modbus Interface EE071 is optimized for use in demanding OEM applications. In addition to the precise measurement of humidity (RH) and temperature (T), the EE071 calculates physical quantities such as dew point temperature, mixing ratio and absolute humidity. All measured and calculated values are available on the RS-485 interface with Modbus RTU protocol. The RH and T sensor HCT01 is perfectly protected against dust and dirt by the E+E proprietary coating. Furthermore, all solder pads are sealed against corrosion. With the appropriate filter cap the EE071 offers outstanding long term stability even in harsh environment. The compact design with M12 connector allows for easy installation and fast replacement of the probe. With the optional Modbus configuration adapter the user can perform RH and T adjustment and set the Modbus parameters.

YOUR PARTNER IN SENSOR TECHNOLOGY, Dimensions in mm (inch)polycarbonate housing - EE071-HTPx Modbus Map The measured values are saved as a 32Bit float value from 0x19 to 0x25 and as 16Bit signed integer between 0x27 and 0x2D. The factory setting for the Slave-ID is 247 as an integer 16Bit value. This ID can be customised in the register 0x00 (value margin 1 - 247 permitted). The serial number as ASCII-code is located at register address 30001-30008. FLOAT (read register): INTEGER (write register): Register address 1) Values are stored with a scaling of 1:100 (e.g.: 2550 is equivalent to...

E+E Sensor Coating The E+E proprietary sensor coating is a protective layer applied to the active surface of the HCT01 sensing element. The coating extends substantially the lifetime and the measurement performance of the E+E sensor in corrosive environment. Additionally, it improves the sensor’s long term stability in dusty, dirty or oily applications by preventing stray impedances caused by deposits on the active sensor surface. Ordering Guide MODEL 1) The metal housing (M) is only available with stainless steel grid filter and with H2O2 filter (L). The stainless steel grid filter is only...
