ISSUE 2 Installation Instructions for the SURSENSE® Ultra Low Pressure Sensors DCAL4 Series WARNING PERSONAL INJURY DO NOT USE these products as safety or emergency stop devices, or in any other application where failure of the product could result in personal injury. Failure to comply with these instructions could result in death or serious injury. GENERAL INFORMATION The DCAL4 Series sensors provide a precisioncalibrated, ratiometric 4 V output based on SURSENSE®, a proprietary technology. Each sensor features the precision calibration found in the DCX Series with the addition of fully integrated signal conditioning in an industry-standard package. Intended to operate from a fixed 5.0 Vdc supply, the DCAL4 gage pressure sensors provide a 0.25 V to 4.25 V output while the differential versions provide a ± 2.0 V output centered on a 2.25 V zero pressure offset. These highly stable sensors are ideally suited for microprocessor or microcontroller based systems. Product is patented by US patent 6023978. SOLDERING/ASSEMBLY Limit soldering to 315 °C [600 °F] maximum, with duration of five seconds maximum. Leads must be adequately supported during any forming/shearing operation to ensure that the leads are not stressed inside the plastic case.
