1. When selecting the product, please ensure that the medium to be
measured is compatible with the contact parts of the product.2. When placing an order, please note that explosion-proof type
products do not include digital display heads.3. When ordering transmitters with an LCD or LED display head, the
power supply for the transmitter should not be lower than 20VDC.4. To ensure reliable operation of the product, it is recommended
that users install lightning protection devices on-site and ensure
that the product and power supply are reliably grounded.5. The rated working temperature range of the Fluoro rubber O-ring
is -20ºC to 250ºC. When the product's operating temperature is
below -20ºC, it is necessary to choose an EPDM O-ring seal.6. For special requirements such as strong vibration, instantaneous
impact force, strong electromagnetic or radio frequency
interference, please inform our company and specify them in the
order.
