What SignalFire does

SignalFire Wireless Telemetry, founded in 2006 and headquartered in Marlborough, Massachusetts, is an industrial wireless telemetry company operating as a subsidiary of TASI Measurement, a diversified industrial measurement group with 15 business units and production facilities across the US, Canada, Switzerland, Germany, and England. The company designs and manufactures wireless hardware and cloud software for monitoring remote assets in harsh environments, serving oil & gas, water & wastewater, environmental, refining & petrochemical, agriculture, tanks & terminals, utilities, and general industrial customers in more than 20 countries. SignalFire's portfolio of 60+ products is built on two complementary platforms: a proprietary 900 MHz low-power wireless mesh/star network with a self-configuring, self-healing protocol developed in-house, and a cellular LTE-M1/NB-IoT line branded RANGER that connects sensors directly to cloud or SCADA systems.

SignalFire's technical stack combines a hybrid mesh/star radio architecture with low-power firmware that supports 5-10 year battery life, remote HART device tunneling over 900 MHz or cellular LTE via PACTware/Fieldcare/Radar Master, and the PATRIoT Gateway for aggregating Modbus TCP, EtherNet/IP, and MQTT/Sparkplug at up to 30,000 tags. Hardware spans wireless nodes, gateways, pressure and flow sensors, the AirQ Scout family of Class I Division 1-certified wireless gas detectors, the Tilt Scout inclinometer, and remote shutdown systems. Software includes the SignalFire Cloud platform, built on Ignition by Inductive Automation and hosted on AWS with three years of data retention, and the SignalFire Toolkit for local device configuration. The company has logged more than 5 billion cumulative operational hours across deployed systems.

The business model combines hardware sales (wireless nodes, gateways, sensors, and accessories) with a recurring cellular and cloud subscription layer required for the RANGER product line, offered at annual tiers differentiated by data reporting interval. Go-to-market is sales-led through five regional sales managers covering the Southeast US/Latin America, Northeast, Western US/Canada, Permian Basin/Oklahoma Basin, and Midwest, supplemented by approximately 24 manufacturer representative firms across the US, Canada, and Latin America. Class I Division 1 and Division 2 hazardous location certifications, FCC and Industry Canada radio compliance, ISO 14001:2015 environmental certification, and EU export approval for the RANGER line anchor a regulatory position that targets oil & gas, petrochemical, and chemical applications where competitor entry is constrained.

Core offering

SignalFire designs, manufactures, and sells low-power industrial wireless telemetry hardware — 900MHz mesh nodes, cellular LTE-M/NB-IoT transmitters, gateways, gas detectors, pressure sensors, and accessories — bundled with the SignalFire Cloud monitoring/alarming platform. Solutions target remote monitoring of pumps, pipelines, tanks, wellheads, lift stations, and emissions in hazardous (Class I Div 1/2) and general industrial environments across oil & gas, water/wastewater, environmental, refining, and agriculture sectors.

Product overview

SignalFire offers a comprehensive portfolio of industrial wireless telemetry solutions divided into two main technology platforms: (1) Cellular/RANGER products using LTE-M1/NB-IoT for direct cloud connectivity including RANGER Node, RANGER AirQ, DIN RANGER, RANGER 900, PRESSURE RANGER, and RANGER Wall Mount; and (2) 900MHz RF products for local wireless networks including Sentinel, Pressure Scout, Pressure Scout-LR, AirQ Scout, AirQ Scout-LCD, A2 Node Series, and Tilt Scout. Gateway products including Gateway Stick, PATRIoT Gateway, and DIN Gateway V2 aggregate wireless data for integration into SCADA and cloud systems. Accessories include Modbus Stick, Wireless I/O Modules, Multi I/O Stick System, C1D1 Solar Power, Solar Powered Repeater Node, and Gateway Output Modules. SignalFire Cloud provides the software platform for data monitoring, alarming, and remote configuration, while SignalFire Toolkit enables local device configuration and diagnostics.
