Since Critical Environment Technologies Canada Inc. (CETCI) launched the Parkade Emissions Transmitter (PET) in September 2010, interests have spiked. PET is a highly competitive and versatile BACnet® transmitter that is cost effective and is available in five configuration models.
PET BACnet® transmitter is BTL certified, communicates via BACnet® protocol MS/TP and is available with one or two electrochemical or solid-state sensors and temperature sensor. PET features thermal resetting fuse, tri-color LED indicators for power and alarm, optional 4-digit LED display, optional remote solid state sensor housing, and an optional 4-20 mA analog input for solid state sensors. In addition, PET includes a new sensor Calibration Extending Firmware (CEF) that takes into account the aging of the sensors so that less frequent calibrations are acceptable in non-critical applications.
Given that PET is available as a dual sensor transmitter; contractors will only need to purchase one unit, instead of two single sensor transmitter units. This could end up being a 30% cost saving. As a standard feature, both single and dual PET comes with a complimentary temperature sensor. There is no need to purchase and install a separate temperature device. All gas and temperature sensor values will be displayed at the same time, on a single unit. Not only is it cost effective to the contractor but is less time and money spent on installation.
PET is available in five configuration models:
- Single integral electrochemical sensor
- Dual integral electrochemical sensor
- Single integral solid-state sensor
- Single remote solid-state sensor
- Single integral solid-state sensor with 4-20 mA input activated for remote analog transmitter
Electrochemical sensor choices include ammonia (NH3), carbon monoxide (CO), ethylene (C2H4), formaldehyde (HCHO), hydrogen (H2), nitric oxide (NO), nitrogen dioxide (NO2), oxygen (O2), and sulphur dioxide (SO2). This can be either a single or dual integral transmitter.
Solid state sensor choices include combustibles, TVOCs and refrigerants R11, R12, R22, and R134A. This can be either a single integral, single remote or single integral with analog input capabilities. For the later configuration model, any 24 VDC analog transmitters that output 4-20 mA can be connected to the PET and is powered by the PET. The PET in turn, converts the data to the BACnet® protocol along with the integral solid-state sensor and temperature value.
PET is ideal for use in non-hazardous vehicle exhaust environments, commercial HVAC and light industrial applications.
