Selection Examples

Ordering Tips

Ensure the measured medium is compatible with the product's contact parts
Explosion-proof type products do not include digital display heads
For transmitters with LCD or LED display heads, power supply should not be lower than 20VDC
Install lightning protection devices and ensure proper grounding for reliable operation
Fluoro rubber O-ring rated for -20ºC to 250ºC; choose EPDM O-ring for temperatures below -20ºC
Default cable length is 1.5m (polyethylene material); specify alternative materials if required
Inform us of special requirements such as strong vibration, impact force, or electromagnetic interference
