Frequently Asked Questions (FAQ)
Q1: What exactly is a "low flow" transmitter, and how does the EJX115A differ from a standard DP transmitter?
A: A low flow transmitter is specifically calibrated and designed to measure very small differential pressures corresponding to extremely low flow rates, often in the range of milliliters or liters per minute. The EJX115A incorporates a high-resolution sensor and specialized electronics optimized for this sensitivity, whereas a standard transmitter might lack the precision at the lower end of its range.
Q2: Can the EJX115A be used with corrosive media?
A: Yes, but the wetted materials must be specified correctly. The standard model offers certain material options. It is crucial to provide details about your process media (chemical composition, concentration, temperature) so we can recommend or configure the unit with compatible diaphragm and seal materials.
Q3: What communication options are available?
A: The EJX115A series typically offers models supporting the analog 4-20mA signal with HART protocol, the proprietary YOKOGAWA BRAIN protocol, or the open FOUNDATION Fieldbus standard. The specific protocol is determined by the model suffix. Please confirm your system requirements when inquiring.
Q4: Is remote configuration and monitoring possible?
A: Absolutely. When equipped with HART or Fieldbus communication, the transmitter can be configured, calibrated, and monitored remotely using compatible handheld communicators or asset management software integrated into your Distributed Control System (DCS).
Q5: What is the typical installation requirement for this transmitter?
A: Installation requires mounting the transmitter body securely, connecting the process lines to the high and low pressure ports, and wiring the power and signal cables. Detailed mounting guidelines, including considerations for impulse piping to minimize error, are provided in the comprehensive user manual.
Q6: How do I calibrate the EJX115A, and what tools are needed?
A: Calibration can be performed using a precision pressure source and a calibrated readout device. The transmitter itself can be adjusted via its local display/buttons or remotely via communication tools. For highest accuracy, it is recommended to use YOKOGAWA's dedicated calibration software and fixtures, which we can provide information on.
Q7: Are spare parts and technical support readily available?
A: As an established supplier, Rossonix maintains access to genuine YOKOGAWA spare parts. We provide technical support for product selection, installation advice, and troubleshooting, leveraging our experience in serving diverse international markets.
Q8: What is the lead time for delivery?
A: Lead times vary based on model configuration, certification requirements, and current stock levels. We ship from multiple ports including Shenzhen and Hong Kong, facilitating faster delivery to various regions. Please contact us with your specific requirements for an accurate delivery estimate.
