UnitKal/DX - Automatic Calibration for Mining Gas Sensors
Monthly calibration of gas sensors is mandated by MSHA regulations. However, the implementation of this monthly routine can consume a great deal of time and resources. Calibration events are usually scheduled for a specific date, however, there may be delays encountered, causing missed calibration dates and risking safety ...
Rel-Tek - PLC Express Gold for Real-Time Monitoring and Control System
PLC Express Gold is the latest real-time monitoring and control system from Rel-Tek Corporation. PLC Express Gold is a stand-alone unit that can interface with the newest generation of Rel-Tek's intelligent I/O and sensors. The software is Windows ...
RMCalibar - Remote Calibration Panel
Sensors are seldom sited for easy access. Methane and natural gas sensors are normally installed in the roof peaks and skylight areas, because methane is lighter than air. Propane sensors are placed low near the floor and in service pits because this gas is heavier than air. Remote calibration permits each sensor to be calibrated and adjusted without risking accidents with lifts and ladders. There is, of course, no need to stop production and move ...
TelEcon - Model 401 - Stand-Alone Alarm Controller
The TelEcon-401 is our low cost stand-alone controller. This unit is ideal for monitoring 1-4 sensors of any type that has a 4-20 mA output. The programmable RM420i controls alarms depending upon how many modules are installed in the enclosure. The TelEcon-401 can be powered by 110VAC/ or 24VDC. There is also an optional back-up battery re-chargeable system. The size of the panel is depended on the number of modules used. Since many customers' needs ...
Rel-Tek - Model RM420i - Relay Modules for Compact Circuit Board
The RM420i relay modules are compact circuit boards with intelligent electronics and logic for monitoring 4-20mA current loop. Two settable trip points activate SPDT relays. Measures 2.5x3.5x1' (LWH), with corner #6 mounting holes on 2x3.1' centers. Power supply: 12-30VDC; drain 5mA (relays off) to 28mA (relays on). Power increases 20mA while setting thresholds. Relay contacts are rated at 120V, ...
MagiKal - Automatic Gas Sensor Calibration
Rel-Tek's MagiKalTM system takes the labor out of gas sensor maintenance. Repetitive and tedious 'manual' sensor recalibration can cost a bundle over the life of a system. It eliminates the costly labor that is otherwise paid out regularly for manually re-calibrating an array of gas sensors installed around your garage, plant, lab, tunnel or mine. MagiKalTM represents a modest extra investment at the outset, but pays for itself again and again over the ...
