Kobata PB-2L, PB-4L Pressure Transmitters
Made in Japan
Manufacturer: Kowata Keiki Seisakusho Co., Ltd.
Model: PB-2L, PB-4L
Model: PB-2L, PB-4L
The electric pressure gauge (PB-2L, PB-4L) effectively converts changes in measured pressure into a standard electric signal (4-20mA), making it ideal for remote monitoring, control, and pressure processing, as well as for generating abnormal alarms. Both the PB-2L and PB-4L cater to general industrial measurement needs and are also suitable for marine use. The containers, crafted from aluminum cast, ensure the devices are waterproof, lightweight, and compact.
These pressure transmission devices include a high-quality Bourdon tube that converts pressure changes into displacement. Additionally, they feature an electric displacement meter (LINEARIZER) that translates this displacement into a standard electric signal, with various reliable electronic circuits compactly integrated. Consequently, the PB-2L and PB-4L pressure transmitters accurately measure changes in received pressure as a standard electric signal of 4 to 20mA. Moreover, the pressure transmitter’s external load resistance remains constant current up to 400Ω.
