All D3 models feature a zero-bleed pneumatic relay, suitable for linear or rotary valves, single- or double-acting actuators, and special applications; all featuring the same easy-to use user interface for local configuration with Communication via HART®, Profibus PA and DP, Foundation Fieldbus and Wireless ISA100™ is possible.

D3E hazardous area explosion proof is multi approval rated:
ATEX: II 2G Ex d IIB+H2 T6 Gb (-20°C to +60 °C) II 2D Ex tb IIIC T100°C Db (-20°C to +80°C)
CSA, FM: Class I, Div.1 Grps B, C, D Class II, Div.1 Grps E, F, G Class III, Div.1 T6, T5 / Type 4X

Being that the D3 positioner is extremely low air/energy consumption – zero bleed – it meets the EPA 6.0 SCFH leak limit standard, hence can use NG as supply medium. The D3E has been approved to CSA standard for use on natural gas, when configured with the required ancillary components. This configuration done by us in our plant, following which each positioner being inspected and certified to CAN/CSA C22.2 No. 30-2020

Series PTS02 is a Programmable Temperature Switch & Transmitter offering an analog 4-20 mA output, transistor or relay switch output, and an optional RTD output. Utilizing patented MIST technology, PTS02 is designed for optimum accuracy and performance. Shipped factory calibrated to customer specified temperature ranges. Unique feature of the PTS02 is that it is re-programmable. Process temperature or alarm change? No problem! Calibration is password protected using the PTS02-PKIT interface module and re-range your PTS without the need to recalibrate and without the loss of accuracy. When it is re-scaled to a different temperature range, the calibrated default values are not lost. This transducer can be re-calibrated by performing one-point or two-point calibration using known temperature standards. This is where the PTS02 leaves the competition behind. Indicating temperature range, current output, switch set point, switching hysteresis, switch logic, damping and other features are all programmable.
The PTS02 wetted parts, as well as the housing, are fabricated from 316 stainless construction. Other materials, various probe diameters, fitting sizes and thermowell types are available. For electrical connection, a 1/2” NPT conduit with lead wires is standard. The sensing element used is Pt-100 Ohm RTD Class A. PTS02 can be made available with an additional 3-wire RTD output. This feature allows a single process connection to be used for indication of temperature and for remote indication, recording, or controlling. Each PTS02 has the part number, range and serial number marked on the transmitter housing.
This product is protected under US patent 7,223,014 and CDN patent 2,561,570.

The PMV D3E is a CSA approved Non Incendive – CL I, Div 2, Groups A,B,C,D, Intrinsically Safe – CL I, Div 1, Groups A,B,C,D approved digital and SMART positioner.

The D3E explosion proof digital positioner is supplied in a die-cast housing is treated with a powder epoxy, protecting the unit from corrosion and mechanical damage. The D3ENE is an all 316 SS explosion proof positioner and is ideal for very corrosive environments, off shore applications and is of a marine grade design.

DTM-Valve-Sight is an optional feature that provides the D3 digital positioner with optional on-board pressure sensors with unique diagnostic capabilities. The DTM is available for free download, which includes Advance Diagnostic DTM, as e.g. Step- and Ramp tests.

Other features and options include failfreeze on loss of signal, profibus and  foundation fieldbus protocols.

OPSIS is a global supplier of environmental monitoring systems for gas analysis and related services. Systems are calibrated to either single or multiple gas parameters and use Differential Optical Absorption Spectroscopy (DOAS) Additional gas compounds that need to be measured can usually be added in the field without returning the system.  Since monitoring is done by DOAS, and not extraction of gases, resulting measurements are in real time.

A number of systems are available to monitor various environments. Open Path Fenceline Gas Detection, which monitors the perimeter, known as  Fence-line monitoring using an open-path monitoring system is an excellent tool for monitoring the air quality, as well as fugitive emissions and gas leaks.

Of critical importance is the real-time monitoring of fugitive emissions from oil refineries, is Benzene, known as Benzene Fence line Monitoring

The optical scintillation technique uses measurements of turbulence movements found in the emission gas flow stream to give highly accurate measurements of mean path air velocity.

– Uses optical scintillation principle compliant with EPA Method 14 and traceable to NIST
– Non-intrusive, non-contact method, with no direct exposure to gases emitted by stacks or processes
– Measures stacks from 0.5 to 10 meters in diameter
– Conditions such as temperature, pressure, gas composition, vapors, densities, dust or humidity do not compromise flowmeter accuracy or operation
– Operates with emissions and gases up to 95% opacity.
– Very simple installation
– Very low maintenance
– Can be isolated by a knife gate valve
– Unaffected by non-uniform flow velocity profiles caused by elbows, transition ducts, valves and other obstructions.
