DW368 Micro differential pressure transmitter
The DW368 series of differential pressure transmitters utilizes variable capacitance sensing technology, featuring a two-wire 4~20mA signal (four-wire 4~20mA when powered by 220V AC) and a minimum measuring range of 0~25Pa. This MEMS sensor boasts superior sensitivity and long-term stability. The embedded stainless steel housing structure meets GMP standards for clean environments such as clean rooms and operating rooms. The product is elegant and features two relay signal outputs, allowing for arbitrary setting of alarm values. The night display window has dual-color backlighting, white and red, which can change color according to the preset alarm points on site, making it easier to control and adjust the differential pressure within the room. An optional buzzer alarm is available.
Product Overview
The DW368 series of differential pressure transmitters utilizes patented variable capacitance sensing technology (utility model, patent number ZL201520624816.1). This MEMS sensor boasts superior sensitivity and long-term stability. The embedded stainless steel housing structure meets GMP standards for clean environments such as clean rooms and operating rooms. The product is elegant and features two-channel relay signal output, with alarm values that can be set arbitrarily. The night display window has two color backlights, white and red, which can change color according to the alarm points set on site, making it easier to control and adjust the differential pressure in the room. A buzzer alarm is optional.
