New Transmitters Are Designed To Operate In Hazardous Areas
Tel-Tru Manufacturing Co. has expanded its Silicon Glass Fused Sensor series of pressure transmitters with the launch of Intrinsically Safe instruments, which are specifically designed to operate safely in hazardous areas. 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. The two models come with a three-year warranty. The P612 model 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. The P622 model 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.
