2 Handling Instructions
EE895 is an ESD sensitive device and must be handled with corresponding precautions. Protect the
sensor outside the EPA (Electrostatic Protected Area) using ESD protective packaging.
The EE895 is packed in stacks of ESD trays with 50 pieces each. The tray dimension is 354.2 x 278.6 x
23.8 mm (13.94 x 10.97 x 0.94 inch)
Operating and storage conditions: -40…60 °C (-40…140 °F)
0…95 % RH (non-condensing)
700...1 100 mbar (10.15...15.95 psi)
NOTICE
Failing to follow the instructions in this user manual may lead to measurement inaccuracy and device
failures.
▪
The EE895 housing and the circuit board shall not be exposed to unneccessary mechanical stress during
installation and operation. The forces exerted shall not exceed 50 N.
▪
The sensor module deploys a fine dust filter for sensing element protection. If the EE895 is deployed in a
device which is designed for harsh environments, the device shall deploy a filter as well.
