INTRINSICALLY SAFE PRESSURE TRANSMITTER
K1 SERIES
DESCRIPTION
The Ashcroft K1 Series intrinsically safe pressure
transmitter is exceptionally stable and is virtually unaffected
by shock, vibration, or orientation. Performance is directly
traceable to NIST standards, and a calibration certificate
is available for each unit upon request. These intrinsically
safe (IS) transmitters are ideal for monitoring pressures in
explosive atmospheres with barrier.
FEATURES
• Class I, Division 1, Groups C, D;
Class II, Division 1, Group G; Class III
• Nonincendive for Class I, Division 2, Groups A, B, C,
and D
• 0.5% accuracy, all ranges
• 4-20 mA, loop powered
• Ranges from 100-3000 psig (690-20,685 kPa)

CAUTION: Intrinsically safe devices require the use of an
intrinsic safety barrier when applied in hazardous locations.
Provide wiring and grounding strictly in accordance with
manufacturer's instructions. When a K1 Series transmitter
is combined with the Model MTL7706 intrinsic safety barrier,
total cable capacitance between the two must be limited to
0.12 µF. Total cable inductance must be limited to 4.0 mH
(equivalent to 2700'/823m maximum Belden™ #8760 18/2
shielded twisted pair cable 0.18 µH/FT, 44 pF/FT).
