DTG-RTD100 Digital RTD Thermometer w/NEMA 4X Enclosure

Supported Applications

The Omega DTG-RTD100 Series is a digital temperature gauge designed for industrial applications, featuring an RTD sensor and a large LCD display. The series supports measurement in processes involving water, oil, steam, gases, and chemicals.

Operating Conditions & Performance

The DTG-RTD100 Series operates within an ambient temperature range of -40 to 85 °C (-40 to 185 °F) with a process measurement capability from -200 to 1300 °C (-328 to 2372 °F). Accuracy is specified as ±0.1% of reading ±0.5 °C or ±0.1% of reading ±0.9 °F, with a resolution of 0.1 °C / 0.1 °F and a response time of 1 second in still air.

The device is rated for an enclosure rating of IP67 and withstands shock up to 100 G (11 ms) and vibration from 10-500 Hz at 10 G. Pressure ratings include a working pressure of 1000 psi (6.9 MPa) with a burst pressure limit of 3000 psi (20.7 MPa). Humidity tolerance is rated for 0 to 95% RH, non-condensing.

Configuration Options

The series offers configurable options across sensor types, output signals, mounting styles, and power configurations. Key capabilities include:

• Sensor & Wetted Materials: 316L stainless steel sheath with wetted materials including 316L stainless steel and PTFE.
• Process Connections: Available in 1/2" NPT male, as well as M12 male or female connectors. Probe dimensions include a diameter of 12.7 mm (0.5 in) with insertion lengths such as 100 mm (4 in).
• Output Signals: Configurable analog outputs including 4-20 mA, 0-10 V, 0-5 V, 0-20 mA, and 1-5 V. Isolated versions are available for 0-10 V, 0-5 V, 0-20 mA, and 1-5 V.
• Power & Battery: Powered by 2 x 8.5Ah NiMH batteries or an external 12-24 VDC supply. In standard mode with 2 x 8.5Ah NiMH batteries, life is approximately 1000 hours; Li-ion options provide up to 2000 hours.
• Wireless Options: Wireless transmitter variants (indicated by "-W" in model codes) support transmit rates of 1 minute, 5 minutes, 10 minutes, or 30 minutes. Battery life for wireless mode with 8.5Ah batteries ranges from 100 hours at a 1-minute rate to 3000 hours at a 30-minute rate.
• Enclosure & Housing: Features a NEMA 4X enclosure constructed of 316L stainless steel with overall dimensions of 100 mm (4 in) diameter x 150 mm (6 in) height. Weight is approximately 0.5 kg (1.1 lb).
• Certifications: CE, UKCA, and FCC approvals.

Additional accessories include a mounting bracket (Model DTG-RTD100-MB), magnetic stylus, USB programming cable, and battery installation/replacement kits. Replacement parts available for the series include batteries (8.5Ah NiMH or Li-ion), sensor probes, display covers, M12 connectors, and mounting brackets.

Key Product Differences

The DTG-RTD100 Series is distinguished by specific model codes that denote configuration differences:
• Sensor Type & Range: Model numbers include numeric suffixes (e.g., 200, 300, 400, 600, 1200) indicating sensor range or type variations.
• Wireless Capability: Models with the "-W" suffix incorporate a wireless transmitter option; standard models do not include this feature.
• Battery Type: The "-AB" suffix indicates specific battery configurations, such as Li-ion options which offer extended life compared to NiMH in certain modes.
• Connector Style: Variants are available with M12 male (e.g., DTG-RTD100-M12-M) or female (e.g., DTG-RTD100-M12-F) connectors, as well as terminal block connections.
• Mounting: Specific SKUs include integrated mounting brackets or are designed for use with the separate Model DTG-RTD100-MB bracket.
