Signet products are manufactured in a variety of wetted materials to suit various liquids and chemicals.

All plastic materials including typical piping types (PVC, PVDF, PP and PE) are more or less permeable to contained media, such as
water or volatile substances, including some acids. This effect is not related to porosity, but purely a matter of gas diffusion through the
plastic. If the plastic material is compatible with the medium according to the application guidelines, the permeation will not damage the
plastic itself. However, if the plastic encloses other sensitive components, as is the case with Signet plastic paddlewheel sensors, these
may be affected or damaged by the media diffusing through the plastic body and rotor.

PVDF paddlewheel sensor failure when used in hot nitric acid applications has been reported. PVDF is known to allow for substantial
permeation of nitric acid constituents without being damaged itself. No clear guideline can be given here, since the damaging effect
to the sensor is highly dependent on temperature, pressure and concentration. Utilizing sensors in applications with aggressive
substances is possible. On special request Signet can provide sensors with a different internal resin encapsulation (potting) that will
delay the damaging effect of acids to the sensors. For all Special Product inquiries or to place an order, please contact Signet.
