Noshok 626-60-1-1-45-1-G1/2 Intrinsically Safe Pressure Transmitter

The NOSHOK 626-60-1-1-45-1-G1/2 is an intrinsically safe flush diaphragm pressure transmitter for 0–60 psig. It has a 4–20 mA output and a DIN Form A connector with 36″ of cable attached. Its part number includes process connection code 45 (7/16-20 SAE J514 Fig. 34B in the 625/626 table) and a “G1/2” suffix.

Part number breakdown:

• 626: flush diaphragm
• 60: range
• 1: ±0.25% full scale BFSL accuracy
• 1: 4–20 mA
• 45: SAE process connection code
• 1: DIN Form A with 36″ cable
• G1/2: suffix

At 0–60 psig, this is the highest-pressure 626 in this group. Its range is above the 30 psig threshold where NOSHOK lists the G1/2 B flush connection for the 626, rather than the larger G1 B used on very low ranges. Mass Measure’s page does not define the “G1/2” suffix, so confirm the exact process connection, including whether a flush G1/2 B fitting or adapter is supplied, before ordering.

The 626’s flush 316 stainless steel diaphragm, sealed with an NBR O-ring, leaves no cavity for viscous, crystallizing or solids-laden media to collect in. This suits:

• Paints and coatings
• Adhesives
• Slurries
• Food-grade oils
• Wastewater sludge lines in classified areas

At ±0.25% accuracy, readings fall within about ±0.15 psi. On ranges from 5 to 200 psi, proof pressure is 3.5 times full scale.

The pre-wired 36″ lead on the DIN plug simplifies connection to a nearby junction box.

The 625/626 Series is FM and CSA approved as intrinsically safe for:

• Class I, II and III, Division 1, Groups A–G
• Class I Zone 0, AEx ia IIC

Entity parameters are Vmax 30 V and Imax 100 mA.

Other specifications:

• Housing: 316 stainless steel
• Supply: 10–30 Vdc
• Response time: ≤ 1 ms
