Resistance temperature sensor ExSens

ductanalog4-20 mA

Product overview
ExSens passive analog sensors measure temperature, humidity or pressure in hazardous locations and are manufacturer-certified for ATEX environments. These sensors are passive and potential-free; they require connection to a compatible external transmitter (e.g. EXLIM-9182) which converts the sensor resistance into an active 4–20 mA signal (optional 0–10 V).

Key features

• Designed for installation in hazardous zones: sensor placed in the hazardous area, transmitter/module installed in the safe area
• Passive, potential-free sensors requiring an external transmitter to generate an active output
• Signal conversion by transmitter: passive resistance → 4–20 mA (optionally 0–10 V)
• Available for temperature, humidity or pressure depending on sensor model
• Delivery unit: single sensor per order line

Technical specifications

• Measured variables: temperature, humidity or pressure (model dependent)
• Certification: manufacturer certification for use in hazardous locations (ATEX referenced)
• Sensor type: passive, potential-free; requires external transmitter
• Typical compatible transmitter example: EXLIM-9182 (transmitter not included)
• Example sensor models: TFT-2G3D (temperature), TFH-2G (cable temperature), TFK-2G3D (duct temperature), TFM-2G (mean temperature), TFR-2G3D (room temperature), TFR-AN-2G3D (contact temperature), TFFR-2G (temperature and humidity), FFR-2G (room humidity), FFK-2G (duct moisture)
• Ordering example: 1 × FFR-2G for a room humidity sensor
