Application Scenarios

In a Taiyuan central cooling system, the 060G2102​ is typically installed on the discharge line of a refrigeration compressor. It provides real-time pressure feedback (e.g., 0–20 bar range) to the PLC, which modulates the compressor speed via a VFD to maintain optimal condensing pressure, ensuring energy-efficient operation in the variable climate of Shanxi.

Technical Principles and Innovative Values

• Innovation Point 1: Sealed Gauge Reference for Climate Resilience.​ Unlike traditional vented gauge sensors that are sensitive to humidity and dust ingress through the vent hole, the 060G2102​ uses a hermetically sealed vacuum reference chamber. This design makes it immune to clogging from dust or condensation—a critical advantage for outdoor or harsh environment applications in Taiyuan’s dusty industrial areas and wide seasonal temperature swings.
• Innovation Point 2: High Immunity to VFD Noise.​ The transmitter is engineered with robust EMC filtering​ and shielding. When installed near Variable Frequency Drives (VFDs) controlling pumps or compressors, it effectively suppresses RF interference, preventing signal fluctuations that could cause unstable PID control loops.
• Innovation Point 3: Plug-and-Play Angular Connector.​ The Pg 9 angular connector​ allows for flexible cable routing in tight control panels. It prevents the cable from being bent against the panel wall, reducing mechanical stress and the risk of wire breakage, which is a common failure point in high-vibration pump or compressor installations.

 

Application Cases and Industry Value

Case 1: Supermarket Rack Refrigeration in Shanxi.​ A supermarket cold storage system was experiencing frequent compressor short-cycling due to inaccurate low-pressure readings. Replacing a generic sensor with the 060G2102​ (set to a 0–15 bar range for R404A refrigerant) provided stable suction pressure feedback. This allowed the Danfoss AKC controller to precisely regulate the electronic expansion valve, reducing compressor cycling by 30% and cutting energy consumption.Case 2: Industrial Boiler Feedwater Pump Control.​ In a Taiyuan textile plant, the 060G2102​ was installed on the header of a boiler feedwater system. Its 4–20 mA signal was fed into a safety PLC. The transmitter’s high overload capability (40 bar) provided a safety margin against water hammer, while its ±0.3% accuracy ensured the pump protection system would trip accurately at the high-pressure setpoint, preventing dangerous overpressure conditions.
