GE MTS5 series is the upgraded version of the traditional MTS35 analysis host platform, optimized for signal processing accuracy, anti-interference performance and system compatibility. The model code definition: MTS5 refers to the fifth generation digital moisture measurement circuit platform; 321 corresponds to DIN panel installation structure, basic signal processing circuit and standard alarm function configuration; 10 represents factory fixed measurement range parameters and single-channel signal output configuration parameters solidified in firmware. This transmitter forms a complete gas moisture detection system when paired with MMS35, MMS3 series insertion alumina dew point probes.

The internal high-precision signal conditioning module processes weak capacitance signals generated by alumina sensing chips. Combined with real-time temperature data transmitted by the built-in thermistor of the probe, the built-in algorithm automatically compensates measurement errors caused by gas temperature drift. The effective dew point test range covers -110℃ to +60℃, with stable detection performance for ultra-dry compressed air, nitrogen, hydrogen, natural gas, SF6 insulating gas and heat treatment protective gas. It meets the gas quality monitoring requirements of power systems, air separation plants, petrochemical enterprises and pharmaceutical clean workshops.

The main body adopts standard DIN rail panel embedded installation structure, which is convenient for centralized layout inside industrial analysis cabinets. The front LCD display screen can locally display real-time dew point value, ppm moisture concentration, probe working state and system fault codes. Matching physical operation buttons support on-site calibration, alarm threshold setting and equipment self-diagnosis without extra configuration tools. All internal circuit boards are coated with three-proof conformal coating, which resists damp, dust and weak corrosive gas erosion, and runs stably for a long time under the ambient temperature of -20℃ ~ +60℃.

Standard hardware configuration includes isolated 4–20mA analog output channel and reserved RS485 Modbus communication interface. Monitored moisture data can be uploaded to DCS, PLC and SCADA centralized control systems to realize remote data recording, trend analysis and high/low dew point interlock protection. The built-in fault self-diagnosis logic can feed back abnormal conditions such as probe disconnection and signal attenuation through fault codes, lowering the difficulty of on-site maintenance troubleshooting.

This product has passed ATEX intrinsic safety certification. When matched with qualified safety barriers, it can be safely arranged in Zone 1 and Zone 2 flammable and explosive hazardous areas of chemical plants and refineries. The wiring terminals adopt unified standard marking, which is convenient for quick wiring connection with special shielded cables of probes to reduce wiring errors during installation and commissioning. Each MTS5-321-10 is calibrated with NIST-traceable standard moisture gas before delivery, with complete calibration reports provided for user filing and third-party metering audit.

No mechanical wearing parts are arranged inside the transmitter, featuring low failure rate during long-term uninterrupted operation. Daily maintenance only requires regular dust cleaning on the display surface and annual systematic calibration inspection. When the sensing performance of the matched MMS probe declines, users only need to replace the probe core instead of the whole transmitter, effectively cutting spare parts cost and maintenance downtime. It is widely applied to power station SF6 gas monitoring, high-purity gas detection of air separation units, dehydration monitoring of natural gas pipelines and atmosphere quality control of heat treatment furnaces.
