WINLAND ELECTRONICS

Winland Electronics is a manufacturer of environmental monitoring and alerting equipment, with a product history centered on temperature alarms, water detection, and low-voltage power supplies. The company's product families include the WaterBug line of water detectors and alarms, the EA400 series of critical environment temperature alarms, the EnviroAlert Pro (EAPro) ecosystem of wireless sensors, transmitters, and gateways, and a range of regulated plug-in DC power supplies. These products are used in facilities where unattended conditions can cause damage or process disruption: server rooms, walk-in refrigerators and freezers, mechanical rooms, laboratories, and light industrial spaces. The technical profile of the line is consistent across families. Temperature alarms such as the EA400-12 cover a measurement range of -58°F to 299°F and provide a configurable contact rated 1 A at 30 V DC, allowing direct interface with building management systems, autodialers, or alarm panels. The EAPro wireless accessories transmit sensor data via radio frequency over a range of up to 500 ft and can be powered by battery or plug-in supply, which reduces the need for conduit and cabling in retrofit or hard-to-reach locations. The EAPRO-GTWY gateway connects those wireless sensors to a network for remote tracking of temperature and humidity. Water detection is handled by the WaterBug WB-350, a battery-operated unit that produces an 83 dB alarm at 30 cm and includes Form C relays for remote monitoring; it mounts via a key slot for placement near drip pans, sumps, or under raised floors. Temperature probes include the TEMP-L-W thermistor for gas applications, rated -58°F to 158°F with ±2°F/1°C accuracy and a 1.16-inch probe, and the TEMP-H-S thermistor for surface measurement, rated 32°F to 302°F with the same accuracy and a 3.5-inch probe. The plug-in power supply, SKU 12VDC-KIT, accepts 90 to 264 V AC input and delivers regulated 12 V DC at 1 A with a US plug and positive output polarity, suitable for powering low-voltage DC devices in monitoring and control installations. 3G Electric supplies the Winland Electronics line as part of its industrial equipment catalog, covering temperature alarms, water detectors, wireless environmental monitoring accessories, thermistor probes, and DC power supplies. The catalog presents each item with its manufacturer part number, electrical specifications, and physical characteristics so that maintenance and procurement teams can match components to existing panels, sensor networks, and power requirements. Because the line spans both standalone alarm devices and networked monitoring components, buyers can source individual replacement parts or build out a complete monitoring scheme from the same supplier. 3G Electric ships globally and supports the Winland Electronics range with specification-level product data and quotation service for single units or volume orders.

Frequently asked questions

Common questions about WINLAND ELECTRONICS from 3G Electric.

What is the temperature range and contact rating of the Winland Electronics EA400-12 temperature alarm?

The EA400-12 monitors temperatures from -58°F to 299°F. It provides a configurable contact rated 1 A at 30 V DC, which can be used to trigger an alarm panel, autodialer, or building management input. The unit is a plug-in design that mounts in a standard 2-gang electrical box, so it can be installed in existing wall boxes without custom panel fabrication. It is intended for critical environments such as server rooms, cold storage, and mechanical spaces where temperature excursions need to be detected and annunciated locally or remotely.

How does the Winland Electronics WaterBug WB-350 detect water and what output does it provide?

The WaterBug WB-350 is a battery-powered water detector and alarm that operates on 9 V DC. When its sensor detects water, it produces an 83 dB alarm at 30 cm. It also includes Form C relays for remote monitoring, allowing the alarm condition to be sent to a BMS, alarm panel, or dialer. The unit mounts via a key slot, which permits placement on a wall or bracket near drip pans, sumps, under raised floors, or at the base of equipment. Its battery power source means it does not require a nearby AC outlet for basic operation.

What is the transmission range and power option for Winland Electronics EAPro wireless sensors and transmitters?

EAPro wireless accessories, including the EAPRO-WMFT transmitter and EAPRO-WHS humidity sensor, transmit data via radio frequency over a range of up to 500 ft. They can operate on battery or plug-in power, depending on the installation. This range and power flexibility allow sensors to be placed in refrigerated rooms, remote mechanical areas, or other locations where running signal cable is impractical. The EAPRO-GTWY gateway connects these wireless sensors to a network so that temperature and humidity conditions can be tracked remotely through a monitoring system.

What are the differences between the Winland Electronics TEMP-L-W and TEMP-H-S thermistor probes?

The TEMP-L-W is a thermistor probe intended for gas applications. It covers -58°F to 158°F (-50°C to 70°C) with an accuracy of ±2°F/1°C and has a probe length of 1.16 inches. The TEMP-H-S is designed for surface temperature measurement. It covers 32°F to 302°F (0°C to 150°C) with the same ±2°F/1°C accuracy and a longer 3.5-inch probe. Both are used in HVAC, refrigeration, combustion, and industrial monitoring contexts where a specific mounting style or temperature band is required. Selection depends on whether the measurement point is a gas stream or a solid surface.

What are the input and output specifications of the Winland Electronics 12VDC-KIT plug-in power supply?

The 12VDC-KIT is a regulated DC output power supply with an input voltage range of 90 to 264 V AC, making it usable on common 120 V and 230 V AC supplies. It provides a 12 V DC output at 1 A with positive output polarity. The unit uses a US plug style and has a tip size of 55 x 25 x 43 mm. It is intended for powering low-voltage DC devices such as sensors, transmitters, or small monitoring accessories where a regulated supply is required and a wall-outlet form factor is acceptable.

Can Winland Electronics environmental monitoring components be integrated with a building management system?

Several Winland Electronics products provide outputs that can interface with building management or alarm systems. The EA400-12 temperature alarm has a configurable 1 A at 30 V DC contact. The WaterBug WB-350 includes Form C relays for remote monitoring. The EAPro gateway and wireless transmitters are designed to connect sensor data to a network for remote tracking. These interfaces allow the devices to be used as standalone alarms or as part of a larger monitoring scheme. Integration details depend on the specific BMS or panel inputs available at the site.
