ECFX-250-LN Manning EC-FX Gas Detector, NH3 0/250ppm LCD NEMA 1 Enclosure by Honeywell Analytics
If you use ammonia as part of your refrigeration process, you face several challenges in protecting your plant from the danger and expense of ammonia leaks within cold storage, refrigerated process areas and the engine rooms. Introducing a better, tougher, longer-lasting sensor to cover your needs. The EC-FX-NH3 maintains sensitivity and accuracy — even with rapid changes in temperature and humidity.
Now one tough sensor can work in three harsh environments. With the stability you can count and low cost you want, the EC-FX-NH3 is the new gold standard in ammonia detection.
Features & Benefits
- Responds quickly to ammonia concentrations in low parts per million (PPM)
- Rugged construction for long-term reliability
- ATMOSTM Technology for environmental flexibility
Quick Specs
- Stainless steel enclosure with LCD options
- All-new ammonia sensor with a proprietary electrolyte
- 3-year warranty—twice the warranty of most sensors

| GENERAL SPECIFICATION | |
| USE | Ammonia sensor/transmitter designed for use in industrial refrigeration applications. The EC-FX-NH3 can provide a linear 4/20 mA or Modbus RS-485 signal input into PLC's or SCADA systems. Can also be used with Honeywell controllers to create a complete gas detection system that includes visual/audible notification and relay outputs to activate ventilation. |
| COMMON OPERATIONE | |
| OPERATION | In units without the optional LCD module, status is indicated by LEDs installed on the PCB. In units with the optional LCD, two external push buttons, “Accept” and “Scroll” are used to navigate test functions and operating modes. |
| LCD DISPLAY (OPTIONAL) | 2 line by 8 alpha numeric characters and continuous backlight |
| OUTPUT | 2 Isolated 4/20 mA, 700 ohms max. at 24 VDC. Signal output reduces to 0.5 mA to indicate a fault condition. RS-485, Modbus RTU protocol. |
| ACCURACY | ±5% full scale |
| ENVIORNMENTAL IP RATING | Indoor use, IP 44 in accordance with EN60529:1992 |
| OPERATIONAL | |
| HUMIDITY | 5-100% RH (condensing) |
| TEMPERATURE | -50°F to +120°F (-45°C to +49°C), ATMOS equipped enviro-adaptive technology required for refrigerated areas or outdoors |
| SENSOR PRESSURE LIMIT | 0-10 PSIG |
| STORAGE | 40°F to +120°F (-40°C to +49°C), 20 to 80%RH (non condensing) |
| COMMON MODULE | |
| COMMUNICATION | 4/20 mA output: #18/3 shielded cable (Belden 8770 or equal), cable runs < 1,500 ft. RS-485: for communication cable, use 24 AWG twisted pair, shielded (Belden #9841 or equal), cable runs up to 2,000 ft. For power cable use 14 AWG (Belden #5100UE or equal), cable runs up to 1,000 feet. |
| POWER SOURCE | 24 VDC, 0.5 amp max. |
| ENCLOSURE | NEMA 1, gasketed, #16 gauge steel (standard). Stainless steel, including modified enclosures for low temperatures, ventilation ducts, etc. are available. Weight: 3 lbs. |

| SENSOR WARRANTY | Three years from date of shipment |
| SENSOR VIABILITY TEST | SensorCheck: an internal microprocessor determines the sensor's electrical viability every 24 hours. If the viability test fails, a 0.5 mA signal will indicate a fault. An internal LED will indicate if the sensor is at the end of its operational life or disconnected. |
