safely in hazardous locations
Aug 2, 2010 7:00 AM
Tel-Tru Manufacturing Company has expanded its Silicon Glass Fused Sensor Series of pressure transmitters for sanitary, HVAC, and foodservice applications. Intrinsically safe instruments, specifically designed to operate safely in hazardous areas, are available.
The Tel-Tru P612 and P622 are cCSAus intrinsically safe certified to Class I, Division 1, Groups A, B, C, and D when used with approved zener barrier systems. The two models are the newest additions to Tel-Tru’s P600 Series, which features a single piece 316L stainless steel sensing element with a high output silicon glass fused strain gauge. This combination maximizes cycle life even in the presence of pressure spikes, vibration, and aggressive fluid media. These two models come with a three-year warranty.
This 316L sensor is welded to a 316 stainless steel body and includes no O-rings or seals, providing leak-proof reliability. Three accuracy classes are available, including ±-0.50%, ±-0.25%, or ±-0.15% of calibrated span, and the transmitter can be ordered with pressure ranges to 10,000 psi. Many electrical connections are available, including IP69K options for maximum washdown protection. The P612 is field re-rangeable for application flexibility. Each unit also comes with a calibration certificate (NIST-traceable).
The P622 offers nearly all these features, plus meets the needs of many sanitary applications. It is designed and manufactured in accordance with 3A standards and is compatible with CIP and SIP maintenance procedures. The transmitter can be ordered with pressure ranges to 1,000 psi and with a variety of Tri-Clamp or Cherry-Burrell process connections.
These pressure transmitters are manufactured in Tel-Tru’s Rochester NY factory.
