SensCast Wireless Gas Detection

Industrial Wireless Fixed Gas Detection Solution

Product Description

The SensCast system is a wireless platform designed for robust and reliable gas detection across your entire facility. It eliminates the need for complex and expensive hardwiring, offering a comprehensive solution for continuous, multi-point gas monitoring.

Key Features:

  • Flexible Network Design: Choose between 900 MHz or 2.4 GHz systems to optimize for your specific environment and minimize interference.
  • Strategic Sensor Placement: Remote or locally mounted sensors provide the most effective gas detection coverage, regardless of accessibility limitations.
  • Low-Power Efficiency: Ultra low-powered transmitters with internal power sources ensure long-lasting operation and minimize maintenance needs.
  • Safety-Rated for All Areas: Hazardous area and non-classified area models guarantee compliance and safety in any location within your facility.
  • Scalable Solutions: SensCast adapts to your needs, supporting both short-term deployments and permanent installations.

Safety and Reliability:

  • Facility-Wide Monitoring: Deploy SensCast for comprehensive gas detection across your entire plant, ensuring worker safety and regulatory adherence.
  • Hazardous Area Certification: Rigorously tested and certified for Division 1 and Division 2 hazardous classified areas, SensCast delivers reliable operation in even the most challenging environments.
  • Seamless System Integration: Repeater functions bridge wired systems to DCS/PLC controls, enabling automated responses to gas detection events.
  • Wireless Control & Automation: Wireless relays empower real-time activation of alarms and mitigation procedures for immediate response to gas hazards.
  • Dual Sensor Capability: Select dual-sensor models for independent monitoring of two separate gas types, maximizing safety coverage.

User-Friendly Design for Simplified Management:

  • Reduced Installation Costs: The wireless design eliminates the need for expensive wiring and conduit runs, resulting in significant cost savings during installation.
  • Remote Access & Control: Monitor system status, access real-time data, and configure settings from a mobile device or web browser for unparalleled convenience.
  • Intuitive Interface: The user-friendly, menu-driven system simplifies setup and ensures clear communication of critical gas detection information.
  • Configurable Alarm System: Establish three distinct alarm levels for prioritized notifications based on the severity of a gas detection event.
  • Comprehensive System Analysis: Utilize the SensCast Site Survey Tool (SST) to calculate network reach, identify potential RF interference, and optimize your wireless gas detection network for peak performance.

System Diagram

 

Drawing 1: SensCast Transmitters transmit wirelessly to the SensCast Receiver. The Receiver sends Transmitter output via wifi or Modbus (wireless or wired). The SensCast Relayer actively ?listens? for alarm or fault conditions and activates annunciators or hazard mitigation systems connected to one of 5 relays.

 

Drawing 2: Two independent networks consisting of a Receiver and 32 SensCast Transmitters (or 16 Dual Head Transmitters) exist in one facility. A Sensidyne wireless-enabled controller (Model 7200 shown) collects all 64 outputs sending them to a DCS or PLC via wireless Modbus. A SensCast Relayer actively ?listens? for alarm or fault conditions and activates annunciators or hazard mitigation systems.
