Frequently asked questions

Common questions about OMEGA from 3G Electric.

What types of thermocouple connectors does OMEGA offer, and how do I select the right one?

OMEGA manufactures thermocouple plugs and connectors in standard and miniature sizes, with color-coded bodies (e.g., yellow for Type K) made from alumina ceramic or other high-temperature materials. The NHX-K-M is a standard plug for Type K thermocouples with two chromel pins. Selection depends on thermocouple type (K, J, T, etc.), operating temperature, and whether a clamp or write-on window is needed. OMEGA connectors are designed for reliable signal transmission in industrial environments.

What is the accuracy specification for OMEGA RTD probes like the PR-22-3-100-A-1/8-0600-M12?

OMEGA Long-Life & High-Accuracy RTD probes, such as the PR-22-3-100-A-1/8-0600-M12, offer accuracy of ±0.15°C at 0°C for surface models like the SA1-RTD-120, and ±0.55°C over the full measuring range for threaded probes like the PRTXI-1/2N-1/4-3-IO. These probes use 316 stainless steel sheaths and are available with M12 connectors for easy integration. Accuracy is specified at reference conditions and may vary with temperature extremes.

Can OMEGA digital panel meters like the DP32PT be used in outdoor or washdown environments?

Yes, the OMEGA DP32PT multi-function digital panel meter features a NEMA 4X rated enclosure, making it suitable for outdoor and washdown environments where moisture and dust are present. It operates on 90-240 V AC and has a green LED display with a span of -1,999 to 9,999. Accuracy is 0.03% FS. The meter includes USB connectivity for data logging and configuration.

What temperature ranges do OMEGA thermocouples for gas applications cover?

OMEGA standard thermocouple probes for gas applications, such as the 5SC-TT-K-36-36 Type K, are rated up to 500°F (260°C). For higher temperatures, OMEGA offers probes like the WTK-6-36 for surface applications, rated up to 900°F (480°C). These thermocouples use fiberglass insulation and are available with bolt or other mounting options. Always verify the maximum temperature rating for the specific model and media type.

How do OMEGA temperature transmitters like the M12TXSS-PT100-13MM-1/8NPT integrate with existing systems?

The OMEGA M12TXSS series temperature transmitter is an RTD-based probe with a 4-20 mA output, operating on a loop-powered supply. It features a 13 mm sensing element and a 1/2 in NPT extension lead for process mounting. Accuracy is ±0.2°C or ±0.2% over a range of -50°C to 120°C. The M12 connector simplifies wiring to PLCs or DCS systems, and the 316 stainless steel sheath ensures durability in industrial environments.
