  • Page 10: Ambient Temperature / Temperature Classes

    DEVICE DESCRIPTION OPTISWIRL 4200 2.6 Ambient temperature / temperature classes Because of the influence of the temperature of the product, no fixed temperature class is assigned to vortex flowmeters. The temperature class of these devices is rather a function of the product temperature and ambient temperature that is present and the specific device version.
  • Page 11 DEVICE DESCRIPTION OPTISWIRL 4200 The permitted ambient temperature range is indicated on the nameplate; depending on the device version it is T = -40...+65°C / -40...+149°F. The minimum product temperature is -40°C / -40°F. When using in zone 21, observe the maximum permissible product and ambient temperatures for temperature class 2 and the information for use of a heat-resistant connecting cable and cable entry.
