Description

Pressure transmitter for general applications

Monitoring of relative pressure in gases, vapors,

liquids and dust

process

temperature

Protection

IP69K

pressure

up to

bar

600

Due to the device construction with

measuring ranges from 1 bar to 600

bar (gauge, adjustable), process

temperatures from –25°C to +100°C,

process materials Al2O3-ceramic /

CrNi-steel as well as the availability

of industrial standard process

connections like thread ISO 228-1, EN

837 manometer, thread ISO 228-1,

DIN EN ISO 1179-2 E or thread metric

resp. ANSI NPT the device is especially

suitable for the use for machinery and

plant engineering, air-conditioning

and refrigeration plant engineering,

hydraulic and pneumatic systems,

process industry or environmental

technology.

The pressure transmitter is suitable for

cost sensitive as well as demanding

measuring requirements.

Due to its high accuracy and the

digital adjustability by a FSK operating

unit or by RS485 Modbus RTU, the

device can be suited a wide variety of

applications.

The robust design and the high-quality

workmanship turns the device into

a very high quality product, which

even the most adverse environmental

conditions cannot aect, whether

the lowest temperatures when used

outdoors, extreme shock and vibration

stress or aggressive media.

A captive laser marking of the type

label ensures the identiability

throughout the entire lifetime of the

device.

Obviously is the optional marking of a

measurement point designation resp.

TAG, a customer label or of a neutral

type label, of course also per laser

marking, possible.

A LABS-free resp. silicone-free

version, a factory calibration with

calibration certicate and a customer

specic conguration resp. preset is

also optionally available like a material

test certicate EN10204 3.1.

Customer specic special versions

can be realized on request, e.g. other

connector, other process gasket

(EPDM, NBR, FFKM, etc.) or special

designs for the process connection.
