Ordering tips
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.
