Industrial 4-20mA Transmitters for a Wide Range
of Toxic Gases
 |
It
is essential to prevent any risk of asphyxia, poisoning or explosion due to
the presence of gas in order to ensure safe operations.
OLDHAM has developed its SERIES 20, a new generation of gas
detectors designed for production and other industries to cater for all
detection requirements at an excellent price.
These are rugged 4-20mA transmitters in all-metal housings
and come supplied with pre-calibrated sensors and a 15m cable. There
is a wide range of gases available, including flammables and toxic gases.

Series OLC20 and OLCT20
|
c Cell Unit OLC
20
The new generation of OLC 20explosimetric cell units is
unaffected by poisons.
The units provide extremely quick response times and complete
reliability.
They can be fitted on a housing with a M25or 3/4’’ NPT
thread. |

c Detector
OLC 20D
Based on the OLC 20cell unit, the OLC 20Ddetector is equipped
with a 15m long cable (standard version) and stuffing gland for direct
connection to a data logger.
A high-temperature version allows operation at 200°C. |

c
Transmitter cell unit OLCT 20
The OLCT 20cell units, which are fitted with precalibrated
cells (explosimetric, toxic or oxygen type), are classified as flameproof or
intrinsic safety according to your needs or the gases detected.
As in the case of the OLC 20, they are fitted on the housing
by a M25or 3/4’’ NPT thread.
c
Detector-transmitter OLCT 20D
Based on the OLCT 20cell unit, the OLCT
20Ddetector-transmitter is equipped with a 15m long cable (standard version)
and a packing gland for direct connection to a data-logger.
Wiring Connection Depending on the Type of
Area
New generation : New Advantages
The cell units of 316L stainless steel provide robustness and
resistance to corrosive agents. Classified IP 66, they are resistant to dust
and water ingress.
The precalibrated cells of the OLCT 20 and OLCT 20D are disconnected by
turning the head of the unit.
These cells, which are equipped with a printed circuit, can be calibrated,
on a autonomous bench, outside hazardous areas.
