DMV 4000 series
Amplifier and pressure gauge DMV4000 is a succesor of DMV 3000, it is based on the microprocessor construction and it is very easy to operate
It is an amplifier for material flow pressure controlling converters. Universal possibilities of settings assure the conversion of 1 to 4 mV signal in the output connection. The device has max. 4 (any) options of alarm output and (optional) one analogue signal of 0-10 V, 0-20 mA or 4-20 mA. High value of the memory, easy handling with sensible touch keyboard and the extreme durability of construction assure satisfaction and easy use. The unit may be protected against the non-authorized usage.
