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.

Critical Environment Technologies Canada Inc. (CETCI) is proud to receive the BACnet^® Testing Laboratories (BTL) certification for PET BACnet^® gas detection transmitter on October 15, 2010.

BTL was established by BACnet^® International to test product functionalities based on the BACnet^® standards. BTL’s mandatory requirements must be met in order to be BTL listed.

PET BACnet^® gas detection transmitter has passed the BTL requirements for the BACnet^® Smart Sensor (B-SS) designation. PET is a “Parkade Emissions Transmitter” that communicates via BACnet^® protocol MS/TP and is available with one or two electrochemical sensors or solid-state sensor and temperature sensor. Electrochemical sensor choices include ammonia (NH₃), chlorine (Cl₂), carbon monoxide (CO), ethylene (C₂H₄), formaldehyde (HCHO), hydrogen (H₂), hydrogen sulphide (H₂S), nitric oxide (NO), nitrogen dioxide (NO₂), oxygen (O₂), ozone (O₃), and sulphur dioxide (SO₂). Solid state sensor choices include combustibles and refrigerants. PET features thermal resetting fuse, tri-color LED indicators for power and alarm, and an optional 4-digit LED display. 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. PET is ideal for use in non-hazardous vehicle exhaust environments, commercial HVAC and light industrial applications.

Every CETCI product is designed to deliver years of reliable operation and is easy to operate.

Critical Environment Technologies Canada Inc. (CETCI) officially launches GEM multi-purpose, self-contained gas detector to add to their growing product line.

GEM is a Gas Emissions Monitor that is economical for non-hazardous commercial applications. Applications include, but are not limited to, parking garages, repair shops, arenas, and manufacturing plants. It is available in one or two channel configurations accommodating accurate “smart” sensors. Features include CSA/UL/CE certifications, integral and/or remote sensors, two 5-amp dry contact relays,4-20 mA linear output signal, and optional 4-digit LED display. It includes new sensor CEF (Calibration Extending Firmware) that takes into account the aging of the sensors so that less frequent calibrations are acceptable in non-critical applications.

Delta, B.C. – Critical Environment Technologies Canada Inc. (CETCI) will launch their new low cost PET (Parkade Emissions Transmitter) this summer.

The PET is a new economical BACnet transmitter that is available with electrochemical sensors and temperature enclosed in a general purpose ABS enclosure. Sensors available include carbon monoxide, nitrogen dioxide, and sulphur dioxide (more sensors to come). Featuring a thermal resetting fuse and tri-colour LED indicator for power and alarm, the PET transmitter communicates via BACnet protocol MS/TP signaling. A 4-Digit LED display is optional. Calibration and maintenance procedures are easily performed in the field.

The PET BACnet, digital gas detection transmitter is ideal for use in non-hazardous (non-explosion rated) vehicle exhaust environments, commercial HVAC and light industrial applications. Every CETCI product is designed to deliver years of reliable operation and is easy to operate.

Choosing the right enclosure maybe as important as selecting the right product. An electronic enclosure, also known as housing, helps protect the circuit board allowing it to function properly. Elements (e.g. water, wind, dust, dirt, heat, cold, humidity, and chemicals) in the surrounding environment could damage or deteriorate the product (see Figure 1).

For example, large temperature variations between the inside and outside of the enclosure can result in pressure differences that may create a vacuum and draw water through the fittings or component and gasket seals. Or when moist air reaches its dew point, it can no longer hold its form and forms moisture droplets being formed on any available surfaces. This is called condensation. When temperatures are below freezing, it will condense into frost. After time, corrosion occurs and causes electrical resistance, which in turn generates additional heat, product performance problems, rusting, increasing risk of circuit shorting out, and arcing and sparking incidences.

Here are six factors to think about before choosing an enclosure:

• Environment
• Application
• Thermal management requirements
• Enclosure performance standards
• Material
• Size

APPLICATION
Application can be associated with market or product. Market applications would be locations such as water treatment plants, parking garages, pools, arenas, repair shops, food plants, etc. Product applications would be physical enclosure requirements such as wall mount, duct mount, easy access, etc.
