AI Overview
A sealed flameproof temperature modulator (or controller/transmitter) is a ruggedized, explosion-proof instrument designed to measure, display, or control heat in hazardous industrial environments, such as petrochemical or pharmaceutical plants
. These devices often feature IP-rated housings (aluminium or stainless steel), 4-20mA transmitters, and comply with safety standards like ATEX, IECEx, or UL/CSA for use in explosive gas or dust atmospheres.Key Features and Types
- Flameproof Enclosure: Protects internal electronics and prevents ignition of surrounding hazardous environments (Ex db/Flameproof).
- Temperature Controllers/Limiters (e.g., BARTEC DTW): Used for freeze protection or heating control, often with 22A switching capacity.
- Temperature Transmitters (e.g., Pyropress PYRT): Converts temperature sensor input (RTD/TC) to a 4-20mA signal, with some featuring local LED displays (e.g., Ace AI-01-F).
- Hermetically Sealed Sensors: Many models use hermetically sealed switches for protection against contamination.
- Applications: Ideal for hazardous zones (Zone 1/21, Class I/II/III).
Typical Technical Specifications
- Certifications: ATEX, IECEx, UL, CSA, SIL2.
- Material: Aluminum die-casted or 316 Stainless Steel.
- Output/Display: 4-20mA, Relay Outputs (NO/CO/NC), Local Digital Display.
- Temperature Range: Often ranges from todepending on the sensor and application.
