Product Image The DELTA series of pressure gauges are mainly used to monitor and control low pressure differentials, which have high requirements for unilateral overload and static pressure. The typical markets for these products are the process heating technology, heating, ventilation and air conditioning industry, water/wastewater industry, as well as machinery manufacturing and factory construction. For these, the main function of measuring instruments is to monitor and control filters, compressors, and pumps. As long as the circuit needs to switch safely according to the specified pressure difference, DELTA switch can be used. When the pressure exceeds or falls below the set point, the switch operation is triggered. Special features With one or two adjustable microswitches. Shatterproof window and robust aluminium or stainless steel measuring chamber for increased requirements. Optionally with approvals for hazardous areas. High ingress protection, IP65, for outdoor use and processes with high condensation. Low measuring range from 0 ... 250 mbar. Core Advantages Dual display and cost savings: It measures differential pressure and working pressure simultaneously, eliminating the need for separate pressure gauges and measuring points. Mechanically reliable and operational without power supply: Adopting a purely mechanical design, it requires no power source and keeps monitoring running even during power outages (ideal for critical safety scenarios). Overpressure Resistance: Each side can withstand full static pressure, making it suitable for high-pressure side working conditions of fans, filters and other equipment. Front-adjustable and easy to maintain: The switching point can be adjusted from the front without disassembling the device, enabling quick on-site calibration. Robust protection for outdoor use: IP65 rating plus shatterproof window, suitable for humid, dusty and condensing environments. Applications Boilers and pressure vessels. Drinking and cooling-water treatment plants. Pressure-boosting and pumping stations. Heating technology. Fire-extinguishing systems. For quotation, send the complete order code, quantity and operating conditions. Specifications and available options depend on the ordered configuration.
