Working temperature: -55 ℃~+121 ℃, resistant to 2500g impact
Installation: Any angle (horizontal/vertical/diagonal installation is acceptable, with no mechanical moving parts)

4、 Shutdown&Replacement Status
The old factory code 330500-01-04 is gradually being replaced with a new model: 330500-01-CN (a domestically standardized new version with fully compatible parameters and direct replacement)
The original factory has not completely stopped production, and imported stock, brand new inventory, and dismantled spare parts are all in circulation; Priority will be given to purchasing 330500-01-CN as a replacement for the renovation of old equipment.

5、 Supporting systems and applications
1. Adapt monitoring card components
Equipped with Bentley 3500/42M, 1900/65A, 2300/20 vibration monitoring modules, connected to the 3500 unit protection system.
2. Usage scenarios
Thermal power/gas turbine: absolute vibration monitoring of turbine, fan, motor bearing housing
Petrochemical: reciprocating compressors, large pumps, gearbox casing vibration
Metallurgy/Oil and Gas: State Inspection of Turbocharging Units and Large Rotating Equipment (Explosion proof Condition Preferred 04 Explosion proof Suffix)

6、 Differentiation of suffixes within the same series
330500-01-00: Ordinary non explosion proof, 2-pin plug
330500-01-04: Explosion proof intrinsic safety model (this model), dedicated for explosion-proof areas
330500-02-04: M8 installation thread explosion-proof version
