[. . . ] In case the repair or service works should appear inadequate or faulty and should this cause malfunction or nonfunction of the product to which the service was performed Vaisala shall at its free option either repair or have repaired or replace the product in question. The working hours used by employees of Vaisala for such repair or replacement shall be free of charge to the client. This service warranty shall be valid for a period of six (6) months from the date the service measures were completed. This warranty is however subject to following conditions: a) A substantiated written claim as to any alleged defects shall have been received by Vaisala within thirty (30) days after the defect or fault became known or occurred, and b) The allegedly defective Product or part shall, should Vaisala so require, be sent to the works of Vaisala or to such other place as Vaisala may indicate in writing, freight and insurance prepaid and properly packed and labelled, unless Vaisala agrees to inspect and repair the Product or replace it on site. This warranty does not however apply when the defect has been caused through a) normal wear and tear or accident; b) misuse or other unsuitable or unauthorized use of the Product or negligence or error in storing, maintaining or in handling the Product or any equipment thereof; c) wrong installation or assembly or failure to service the Product or otherwise follow Vaisala's service instructions including any repairs or installation or assembly or service made by unauthorized personnel not approved by Vaisala or replacements with parts not manufactured or supplied by Vaisala; d) modifications or changes of the Product as well as any adding to it without Vaisala's prior authorization; e) other factors depending on the Customer or a third party. Notwithstanding the aforesaid Vaisala's liability under this clause shall not apply to any defects arising out of materials, designs or instructions provided by the Customer. This warranty is expressly in lieu of and excludes all other conditions, warranties and liabilities, express or implied, whether under law, statute or otherwise, including without limitation any implied warranties of merchantability or fitness for a particular purpose and all other obligations and liabilities of Vaisala or its representatives with respect to any defect or deficiency applicable to or resulting directly or indirectly from the Products supplied hereunder, which obligations and liabilities are hereby expressly cancelled and waived. Vaisala's liability shall under no circumstances exceed the invoice price of any Product for which a warranty claim is made, nor shall Vaisala in any circumstances be liable for lost profits or other consequential loss whether direct or indirect or for special damages.

The barometers with an analog output are available with different scalings between 500 . . . The PTB210 series barometers are also available with a digital output. The PTB210 series barometers offer an excellent solution for outdoor installations. The housing of the barometer electronics provides an IP65 standardized protection against sprayed water. The rugged corrosion-resistant housing in combination with the small size facilitates easy installation and a long lifetime for the barometer. All the barometers are digitally adjusted and calibrated by using electronic working standards. This manual gives the instructions for the use of PTB210 barometers with the analog output.

The sensor features excellent hysteresis and repeatability characteristics and has an outstanding temperature and long-term stability. Silicon diaphragm Thin film metallization Silicon Glass Silicon Vacuum gap Figure 2 The BAROCAP® Pressure Sensor The BAROCAP® pressure sensor consists of two layers of single crystal silicon having a layer of glass between them. The thinner silicon layer creates an integrated vacuum reference chamber, and forms a pressure-sensitive silicon diaphragm. The thicker silicon layer is the rigid base plate of the sensor, and it is clad with a glass dielectric. Thin film metallization has been deposited to form a capacitor electrode inside the vacuum reference chamber. The coefficients of thermal expansion of silicon and glass materials used in the BAROCAP® pressure sensor are carefully matched together to minimize the temperature dependence, and to maximize the long-term stability. The BAROCAP® pressure sensor is designed to achieve zero temperature dependence at 1000 hPa, and its long-term stability has been maximized by thermal ageing at an elevated temperature. 8 ____________________________________________________________________ M210670EN-B Chapter 3 ________________________________________________________________ Installation CHAPTER 3 INSTALLATION Mounting Due to the compact design of the PTB210, all you need to do is to mount the instrument, and to connect the wires. - Remove the pressure fitting, and place the barometer on a desired structure.
