C ASHCROFT' Trust the shield.™ Model IXLdp Ultra-Low Differential Pressure Transmitter <FM> APPROVH) LOOK FOR THIS AGENCY MARK ON OUR PRODUCTS APPLICATIONS: HVAC, fume hood control, lab/clean room pressurization, laminar flow, furnace/stack draft, leak detection, or pollution monitoring, medical equipment, fan tracking, filter monitoring and velocity measurements FEATURES: • Certified 0.25% and 0.5% accuracy • 0.1"-200"-H2O pressure ranges • High overpressure protection • Optional FM approval for hazardous locations • NEMA 4X metal construction • Six types of output signals available • 5:1 turndown option • Variable dampening option • On-board voltage regulation allows use of lower cost, non-precise, unregulated power supply • Hazardous environments Featuring a highly reliable variable capacitance sensor using the patented Ashcroft® SiGlas™ sensor. This ultra-thin single crystal diaphragm provides inherent sensor repeatability and stability. PERFORMANCE SPECIFICATIONS Ref. Temperature: 70°F ±2°F (21°C ±1°C) Accuracy Class (of Span) Two Options: ±0.25%, ±0.5% Includes non-linearity (Terminal Point Method), hysteresis, non-repeatability, zero offset and span setting errors. Stability - Max. Change (Span/year): ±0.25 Standard Ranges (Inches W.C.) Unidirectional Ranges: Custom Ranges: Special range calibrations - see options Response Time: Standard: 250ms Optional variable damping (0-30 sec) - see options ENVIRONMENTAL SPECIFICATIONS Temperature Limits: Storage:    -40 to 210°F Vibration Sweep: Less than 0.2% Span/g temporary effect 10-130 Hz The Ashcroft® Industrial IXLdp was designed for the measurement and control of very low pressure and flow in industrial and process plant environments. The Industrial IXLdp transmitter features a rugged NEMA 4X enclosure, built-in electrical terminal box isolated from the electronics and threaded process connections. The Ashcroft IXLdp transmitter utilizes a state-of-the-art variable capacitance sensor with a glass-clad silicon chip. The Si-GlasTM technology combines the high sensitivity of a variable capacitance transducer with the repeatability of a micro-machined, single-crystal silicon diaphragm. The Si-Glas sensor is composed of sputtered metals and glass molecularly bonded to silicon. There are no epoxies or other organics in the sensor to contribute to drift or mechanical degradation over time. All specifications are subject to change without notice. All sales subject to standard terms and conditions. BULLETIN CT-3    © Ashcroft Inc. 2015 10/15 FUNCTIONAL SPECIFICATIONS Overpressure Limits: Proof differential pressure:    20    psid Burst differential pressure:    50    psid Maximum static (line) pressure: 100 psi Static pressure effect: less than 0.5% Span Mounting Position Effect: 1" W.C. and higher 0.1% Span/g 0.25" up to 0.5” W.C. 0.5% Span/g 0.1" W.C.    0.8% Span/g Note: Calibrated horizontally standard unless otherwise specified.
